Question

Find the slope of the line containing the two points. (If an answer is undefined, enter UNDEFINED.)(1, 5), (−2, 5)

Answer 1

0

Explanation:

We can calculate the slope in the following way:

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

We replace the points and calculate the slope:

`m=(5-5)/(-2-1)=(0)/(-3)=0`

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.
