Answer 1

Answer:

-1/5

Step-by-step explanation:

y2-y1/x2-x1

1-2=-1

-4-1=-5

-1/5

Answer 2

Answer:

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 =    ________

                 5
