Question

(−19, 12), (−9, 1) Find the slope of the line through each pair of points.

Answer 1

To find the slope(m), use the slope formula:

`m=(y_2-y_1)/(x_2-x_1)` And plug in the two points

(-19, 12) = (x₁, y₁)

(-9, 1) = (x₂, y₂)

`m=(y_2-y_1)/(x_2-x_1)`

`m=(1-12)/(-9-(-19))` (two negative signs cancel each other out and become positive)

`m=(1-12)/(-9+19)`

`m=(-11)/(10)`

Answer 2

-11/10

Explanation:

Slope = rise/run

m = (12-1) / (-19-(-9))

m = -11/10
