STEP 1: Recall what are horizontal and vertical lines in geometry from earlier classes.

STEP 2{ Recall what is zero slope

STEP 3: Recall what a horizontal line is

A horizontal line has a slope of zero. As you move to the right along the line, it does not rise or fall at all.

*The equation of a horizontal line is y = b, Where:x is the coordinate of any point on the line b is where the line crosses the y-axis (y intercept).**t of x. Any point on the horizontal line satisfies the equation. Notice that there is no x value which means the equation is independent of x*

STEP 4: Recall what a vertical line is

*A vertical line is one the goes straight up and down, parallel to the y-axis of the coordinate plane. All points on the line will have the same x-coordinate. *

*In a vertical line the slope is undefined. The equation of a vertical line is*

* x = a. where x is the coordinate of any point in the line, a is where the line crosses the x-axis (x-intercept)*

STEP 5: Write if the equation is a horizontal line or a vertical line

Since x = 2 is the equation this is in the form x = a, this means it is a vertical line
