Question

What is the slope of the line that contains these points?

Answer 1

-The final answer for the slope:

`m = -4`

Explanation:

-There are four points on a table:

`(-7, 21)`,
`(-6, 17)`,
`(-5, 13)`,
`(-4, 9)`

-To find the slope, use any two points from the table and use it for the slope formula:

`m = (y_(2)-y_(1))/(x_(2)-x_(1))`

(The two points I use, were
`(-7, 21)` and
`(-6, 17)` for the formula):

`m = (17 - 21)/(-6+7)`

-Then, solve the formula:

`m = (17 - 21)/(-6+7)`

`m = (-4)/(1)`

`m = -4`

So, the final answer for the slope is
`m = -4` .
