Answer: y= -4x + 1

Explanation:

(-1,5) (1,-3)

5-(-3)=8

-1-1=-2

8/-2=-4 negative 4 is the slope. Now find the y-intercept using the formula y=mx + b where b is the y intercept.

so we will plot the y and x values plus the slope to find the y-intercept.

5=-4(-1) + b solve for b

5=4 + b

b=1

so now will write the equation y = -4x +1
