A horizontal line will have the same y-coordinate for all points on that line. In this case, the line passes through the point (2, 2), which means the y-coordinate is 2.
The equation of a horizontal line can be written in the form y = b, where b is the y-coordinate. Since our line passes through (2, 2), we can say:
y = 2
This equation indicates that for any value of x, the value of y will always be 2, thereby creating a horizontal line across the coordinate plane at height 2.
