Question

find the slope of the line through each pair of points (20,8) , (9,16)

Answer 1

slope = -8/11

Explanation:

Using the points: (20, 8), (9, 16)

we apply the slope formula:

$m\text{ = }\frac{y_2-y_1}{x_2-x_1}$$x_1=20,y_1=8,x_2=9,y_2\text{ = 1}6$$\begin{gathered} m\text{ = }\frac{16-8}{9-20} \\ m\text{ = }\frac{8}{-11} \end{gathered}$

slope = -8/11
