Answer:

y = -3x + 8

Step-by-step explanation:

First, find the slope of the equation.

delta y/ delta x  =  (-4-11)/(4-(-1)) --> -15/5

The slope is -3

y = -3x + b

To find b, input the values of one of the ordered pairs

Using (4,-4) :

-4 = -3(4) + b

-4 = -12 + b

8 = b

The final equation is y = -3x + 8
