Answer:
x = -1
Step-by-step 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.
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{6--5}{-1--1} =\frac{11}{0} = und[/tex]
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.
