Question

What is an equation of the line that passes through the points (-1, 6) (−1,6) and (-1, -5) (−1,−5)

Answer 1

x = -1

Explanation:

You can write the equation of the line by finding the slope between the points and substitute it with a point into the point slope form.

`m = (y_2-y_1)/(x_2-x_1) = (6--5)/(-1--1) =(11)/(0) = und`

These points have a slope which is undefined. This means it is a vertical line that crosses through the x-axis at the x-coordinate of both points -1. The equation is x = -1.
