Question

find the slope of the line through the pair of points. (–1, –6) and (1, 12)

Answer 1

Rise over run.
Rise is: \[y_2 - y_1\]
Run is: \[x_2 - x_1\]

So the slope is: \[\frac{y_2-y_1}{x_2-x_1}\]

We know: \[x_1 = -1,\ y_1 = 6,\ x_2 =1,\ y_2=12\ \]

Can you plug them into the formula?

Answer 2

m=18/2 or m=9
