Answer:
y=-2x+8
Explanation:
We want an equation of the form y=mx + b, where m is the slope and b is the value of y when x=0.
The slope of a line through the two given points:
(4,0) and (0,8)
Rise = (8-0) = 8
Run = (0-4) = -4
Slope = 8/-4 = -2
The y-intercept is given by the point (0,8), which tells us that b=8.
The equation is y = -2x + 8
