x = -2.5 is a vertical line. The vertical graph of the equation is shown in the image attached below.
<h3>What is the Equation of a Vertical Line?</h3>
The slope of a vertical line is undefined, therefore, the equation of a vertical line is expressed as x = a, where a is the x-intercept.
Given x = -2.5, the equation suggests it is a vertical line, where the line intercepts the x-axis at -2.5, which is the x-intercepts.
Thus, the graph for x = 2.5 is shown in the diagram below.
