Answer:

y = -2x - 4

Explanation:

The equation is y = mx + b

m = the slope

b = y-intercept

Slope = rise/run or (y2 - y1) / (x2 - x1)

Points (2, -8) and (-2, 0)

We see the y increase by 8, and the x decrease by 4, so the slope is

m = -8/4 = -2

Y-intercept is located at (0, -4)

So, the equation is y = -2x - 4
