Question

Which of the graphs below represents the equation 8x-y=-4?

Answer 1

Graph X

Explanation:

First, convert the equation into slope-intercept form. The first step is the bring the x to the right side by subtracting 8x from both sides: -y=-8x-4. Now multiply both sides by -1: y=8x+4. Now, if you know about the slope-intercept form, you'll know that 4 is the y-intercept and that
`(8)/(1)` is the slope. 8 is the rise and 1 is the run, so the answer is graph X.
