Answer:
y = -5x + 8
Step-by-step explanation:
Slope-intercept form = ('y = x + b')
x being slope; b being the y-intercept.
Slope = rise/run (or y/x)
Take for example the point on the y-intercept, find the next intercepting point.
(0, 8); (1, 3)
In these points, y (rise/fall) decreases by 5. x increases by 1. Using rise/run (or y/x), we conclude that the slope is -5\1.
