The slope is -14.

Explanation:

(Y_2 - Y_1)/(X_2 - X_1)Y2Y1X2X1 = mm, the slope

Label your ordered pairs.

(-2, 2) (X_1, Y_1)(X1,Y1)
(-1, -12) (X_2, Y_2)(X2,Y2)

Plug in your data.

(-12 - 2)/(-1 - -2)12212 = mm

Two negatives become a positive, so the equation becomes:

(-12 - 2)/(-1 + 2)1221+2 = mm

Simplify.

(-14)/(1)141 = mm

mm = -14
