Answer :

ANSWER:

0

STEP-BY-STEP EXPLANATION:

We can calculate the slope in the following way:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We replace the points and calculate the slope:

[tex]m=\frac{5-5}{-2-1}=\frac{0}{-3}=0[/tex]

That the slope is 0 means that it does not form any angle with the horizontal, that is, if we draw a line in a Cartesian plane, then any line that is parallel away from "x" is horizontal.
