Question

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

Answer 1

Answer:

-11/10

Step-by-step explanation:

Slope = rise/run

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

m = -11/10

Answer 2

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

$m=\frac{y_2-y_1}{x_2-x_1}$      And plug in the two points

(-19, 12) = (x₁, y₁)

(-9, 1) = (x₂, y₂)

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{1-12}{-9-(-19)}$   (two negative signs cancel each other out and become positive)

$m=\frac{1-12}{-9+19}$

$m=\frac{-11}{10}$
