Answer:
y = -7x + 0
Step-by-step 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
