C) 1/5

Step-by-step explanation:

Find the Slope (1, 2) and (−4, 1)

Slope is equal to the change in y over the change in x, or rise over run.

              change in y

    m =    

               change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called rise).

               y2 − y1

    m =    

                x2 − x1

Substitute in the values of x and y into the equation to find the s lope.

               1 − (2)

    m =    

               −4 − (1)

Simplify the numerator.

                 −1

    m =    

                −4 − (1)

Simplify the denominator.

                −1

     m =    

                −5

Dividing two negative values results in a positive value.

                 1

     m =

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
