Question

which graph represents the graph of the equation $x = 2$? (four coordinate plane graphs are shown as options)

Explanation:

Step1: Recall vertical line form

The equation $x=a$ represents a vertical line passing through $(a, 0)$ on the x-axis, where $y$ can take any real value.

Step2: Match to the equation

For $x=2$, this is a vertical line passing through the point $(2, 0)$. Among the given graphs, only the fourth option shows a vertical line at $x=2$.

Answer:

The fourth graph (the one with a vertical line passing through x=2 on the x-axis)
