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

Answer:
-The final answer for the slope:
[tex]m = -4[/tex]
Step-by-step explanation:
-There are four points on a table:
[tex](-7, 21)[/tex], [tex](-6, 17)[/tex],[tex](-5, 13)[/tex], [tex](-4, 9)[/tex]
-To find the slope, use any two points from the table and use it for the slope formula:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
(The two points I use, were [tex](-7, 21)[/tex] and [tex](-6, 17)[/tex] for the formula):
[tex]m = \frac{17 - 21}{-6+7}[/tex]
-Then, solve the formula:
[tex]m = \frac{17 - 21}{-6+7}[/tex]
[tex]m = \frac{-4}{1}[/tex]
[tex]m = -4[/tex]
So, the final answer for the slope is [tex]m = -4[/tex] .
