Question

in the accompanying diagram, which is an equation of line (ell)?
options:
(x = 3)
(x + y = 3)
(y = 3)
(x - y = 3)

Explanation:

Step1: Identify line type

The line $\ell$ is vertical.

Step2: Recall vertical line equation

Vertical lines have form $x = a$, where $a$ is the x-intercept.

Step3: Find x-intercept

The line crosses the x-axis at $x=3$.

Step4: Match with options

The equation $x=3$ matches the line's properties.

Answer:

A. $x = 3$
