Question

What is the slope of the line passing through the points (3,-25) and (5, 11)?

Answer 1

Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°)

Answer 2

Slope is change in y over change in x.

From these two points the change in y is 36.

The change in x is 2.

Therefore, m = 36/2 or 18.

That is your slope.
