Question

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

Answer 1

slope = -8/11

Step-by-step explanation:

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

we apply the slope formula:

`m\text{ = }(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{ = }(16-8)/(9-20) \\ m\text{ = }(8)/(-11) \end{gathered}`

slope = -8/11
