Question

How do you find the slope of the line through the following pairs of points (-3,-1) (1,8)?

Answer 1

`m=9/4`

Explanation:

The slope of a line can be determined by using the formula `m=(y_2,y_1)/(x_2-x_1)`, where `m` is the slope, and `(x_1,y_1)` and #(x_2,y_2) are two points on the line.

`(x_1,y_1)=(-3,-1)`
`(x_2,y_2)=(1,8)`

`m=(8-(-1))/(1-(-3))` =

`m=(8+1)/(1+3)` =

`m=9/4`
