00:30. write the following inequality in slope-intercept form. So let me subtract 4x from both sides.
On line A why did he divide all terms by 2? Provide step-by-step explanations. Negative 8 divided by 2 is negative 4, negative 2x minus 4.
Simplify the right side. In 1982, Robert "Bob" Moses (who had been providing additional math instruction to his daughter) joined, Mary Lou Mehrling, his daughter's eighth grade teacher, to help several students with the study of algebra. Have a blessed, wonderful day! Divide each term in by and simplify. This problem has been solved! Now let's do this last character, 2y is equal to negative eight. The slope intercept form of a linear equation has the following form where the equation is solved for y in terms of x: y = a + bx. It's just that the slope is 0. So you just want to find any two points. Converting to slope-intercept form (video. Check the full answer on App Gauthmath.
In the coordinate plane, the only type of line with an equation that can't be converted into y = mx + b form (slope-intercept form) is a line with an equation equivalent to the form x = c, where c is a constant. 5x - 5y is greater than or equal to 70. If x is equal to 0, y is going to be equal to negative 4, you can just substitute that in the graph. Ask a live tutor for help now. So this just means, I don't care what your y is, x is just always going to be equal to negative 2. Write the following inequality in slope-intercept form 5x-5y 70 5. Do my best to draw it, that's a decent job.
You can go up to more than five. And this is the x-axis, that's the y-axis, I forgot to label them. You have to divide every term by 2. His success in producing the first students from the Open Program of the Martin Luther King School who passed the city-wide algebra examination and qualified for ninth grade honors geometry was a testament to his skill as a teacher.
And the answer is you won't be able to because you this can't be put into slope-intercept form, but we can simplify it. At time3:30you said that you can't make it into slope interval form. Rewrite this equation in slope intercept form. Back 2 and then up 4. Let me do a little bit neater. 4. Write the following inequality in slope-interce - Gauthmath. Y is just going to stay at negative 4. So another point is (8, 5 8/9). No, b does not have to be a whole number.
Feedback from students. And just as a bit of a review, slope-intercept form is a form y is equal to mx plus b, where m is the slope and b is the intercept. And remember it is just below the line as you count going up. Does the answer help you? In order to eliminate the coefficient (2) on Y. Since it's going to be a national thing, so I'm going to learn above, since it's greater than only. Try Numerade free for 7 days. The graph has no y-intercepts if c is nonzero, and all real numbers for its y-intercepts if c is zero. So you divide both sides of this equation by 4. We can rewrite this as y is equal to 0x minus 4, where the y-intercept is negative 4 and the slope is 0. Example 1. y = -13 + 7x. Write the following inequality in slope-intercept form - Home Work Help. Are there any possibility that a linear equation can't convert into slope intercept form? The slope is 5/8, so from your y-intercept point, count right 8 and then go up 5.
Shouldnt he divide by 4? So let's start with line A, so start with a line A. The left hand side of the equation, these two 4x's cancel out, and I'm just left with 2y is equal to. So that means that if I change x by positive 1 that y goes down by negative 2.
This exceptional type of line is a vertical line with undefined slope. All right, let's do line B. So let's divide both sides by 2. If I go back 2, I'm going to go up 4. Koorosh, y=5/8x+8/9 is a linear equation. Learn to convert equations like 4x + 2y = -8 into slope-intercept form. Write the following inequality in slope-intercept form 5x-5y 70 y. If I go back negative 1, so if I go in the x direction negative 1, that means in the y direction I go positive two, because two divided by negative one is still negative two, so I go over here. So we divide the left-hand side by 2 and then divide the right-hand side by 2. We can divide both sides of this equation by 2, and we get y is equal to negative 4. We're asked to convert these linear equations into slope-intercept form and then graph them on a single coordinate plane. Still have questions? B is simply where the line will cross the y-axis when this line is graphed. So this is line A, let me graph it right now. The equation y=5/8x+8/9 is is slope y-intercept form.
So if I go over one in the positive direction, I have to go down 2, that's what a negative slope's going to do, negative 2 slope. It is the y intercept, the place where the line crosses the y axis. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign. Subtract from both sides of the inequality. That is line A right there.
Y>\frac{2}{5} x-4$$. So you might say hey, Sal, that doesn't look like this form, slope-intercept form, but it is. So line C, we have 2y is equal to negative 8. How did he get (0, -4) from y= -2x- 4? So x is equal to negative 2 is right there, negative 1, negative 2, and x is just always going to be equal to negative 2 in both directions.
A is a constant term. We solved the question! It's a negative for my style, but it's over five. Also what is the x mean in "y=mx+b".
We just have to get rid of this 2, and the best way to do that that I can think of is divide both sides of this equation by 2. Now we're almost at slope-intercept form. And then we are left with y is equal to negative 4 divided by 2 is negative 2x. And then the slope is negative 2x. Use the slope-intercept method to graph each inequality. Gauth Tutor Solution. The y intercept is (0, -7. We have our coordinate plane over here. In y=mx+b must b be a whole number(4 votes). Solved by verified expert. Write the following inequality in slope-intercept form 5x-5y 70 c. If you choose 0 for x then y=5/8 * 0 + 8/9 = 8/9 so your first point is (0, 8/9). Unlimited access to all gallery answers. The first thing I'd like to do is get rid of this 4x from the left-hand side, and the best way to do that is to subtract 4x from both sides of this equation.
Enjoy live Q&A or pic answer. So we just have to algebraically manipulate these equations into this form. Or you can just interpret it as y is equal to negative 4 no matter what x is. If I go over 2, I'm going to have to go down 4. And you get x is equal to negative 2. So then we are done.
