Answer:

y = -7x + 0

Explanation:

slope-intercept form is y = mx + b where m is the slope and b is the y-intercept

use any of the points on the graph. (0,0) (-1,7). find the slope

slope = y2 - y1/ x2 - x1

slope 7 - 0/ -1-0 = 7/-1 = -7. our slope is -7

so now we already have y = -7x + b. but we still have to find the y-intercept.

-7/1 = y - 7/x - (-1) cross multiply.

y - 7 = -7x - 7

y + 7x = -7 + 7

y + 7x = 0

y = -7x + 0
