Answer: y = -1/4x - 2

Step-by-step explanation:

Using the slope formula to find the slope: (y2 - y1) (x2-x1)

so, -1-(-4)/ -4-8 This simplified is -1/4, this is the slope.

-1 +4=3 and -4-8=-12

We use the y=mx+b to find the y intercept. We can use either one of the points to substitute

-4=-1/4(8) + b which equals -4=-2+b when adding 2 to both sides it results in -2. So the y-intercept is -2.

Final answer in slope intercept is: -1/4x - 2
