Answer: 1/4

Step-by-step explanation: Typing steps

Find the Slope

(−1, −2) , (3, −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 r ise).

y2 − y1

m = -----------

x2 − x1

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

m = −1 − (−2) /3 − (−1)

Simplify the numerator.

Multiply −1 by −2.

m = −1 + 2 /3 − (−1)

Add −1 and 2.

m = 1/3 − (−1)

Simplify the denominator.

Multiply −1 by −1.

m = 1/3 + 1

Add 3 and 1.

m = 1/4
