Chose all that are correct.

−1/5

−1/3

1/5

1/3

Answer 1

-1/5

Explanation:

y2-y1/x2-x1

1-2=-1

-4-1=-5

-1/5

Answer 2

C) 1/5

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.
