This graph represents a vertical line on the Cartesian plane.

This line passes through the point (2,y) for all values of y, meaning it is parallel to the y-axis.

A vertical line is defined as x=constant. In this case, it's x=2, indicating that regardless of the value of y, x will always be 2.

A linear function typically takes the form y=mx+c, where m and c are constants. ...
