The slope is -14.

Explanation:

(Y_2 - Y_1)/(X_2 - X_1) = m, the slope

Label your ordered pairs.

(-2, 2) (X_1, Y_1)
(-1, -12) (X_2, Y_2)

Plug in your data.

(-12 - 2)/(-1 - -2) = m

Two negatives become a positive, so the equation becomes:

(-12 - 2)/(-1 + 2) = m

Simplify.

(-14)/(1) = m

m = -14
