Write the equation of the vertical line that contains the point (-8, -9).
I have been trying to figure out this question but I am stumped can some one go through this with me step by step please?

Plot the point (- 8 , - 9)
Draw a vertical line thro` this point,
Every point on this line has an x coordinate of - 8
Equation of line is x = - 8

A vertical line indicates that the x value (-8) never changes. Since x = -8 and the y value can be anything, the equation of the line is simply x=-8. The proof is that if you plot this equation you will draw the line described exactly by the question.

A vertical line runs parallel to the Y axis. A vertical line always
its x value set to constant value. For (-8, -9), x
is -8, and so the veritical line has every x value set to -8.
The equation is simply:
x = -8

-8 corresponds to the x-axis and -9 to the y-axis. Vertical means the line will be parallel to the y-axis, and will go through the x-axis. This means that the line will go through all points on the y scale, but only one point on the x scale. The equation is therefore x = -8.

x = -8
a vertical line goes straight through x so it will always be x=...
hope i helped
e-mail me if u need anymore help

x=-8
Vertical lines always have the same x point no matter what, and you already are given the x point! YAY!
