Question

Find the slope of the line passing through each of the following pairs of points: (7, −3), (8, −7)

Answer 1

m=-4

(the slope is negetive 4)

Explanation:

Answer 2

`-4`

Explanation:

Start with point-slope form:

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

Identify your values.

`x_1=7\\x_2=8\\y_1=-3\\y_2=-7`

Substitute.

`(-7-(-3))/(8-7)`

The
`-3` becomes positive as it is being multiplied by a negative.

`(-7+3)/(8-7)`

Combine like terms.

`(-4)/(1)`

Rewrite.

`-4`
