$(x, y) = (- 2, - 5), x = 3$

Step 1

Graph $x = 3$ .

Step 1.1

Since $x = 3$ is a vertical line, there is no y-intercept and the slope is undefined.

Slope: Undefined

y-intercept: No y-intercept

Step 1.2

Find two points on the line.

$\begin{array}{c} x & y \\ 3 & 0 \\ 3 & 1 \end{array}$

Step 1.3

Graph the line using the slope, y-intercept, and two points.

Slope: Undefined

y-intercept: No y-intercept

$\begin{array}{c} x & y \\ 3 & 0 \\ 3 & 1 \end{array}$

Slope: Undefined

y-intercept: No y-intercept

$\begin{array}{c} x & y \\ 3 & 0 \\ 3 & 1 \end{array}$

Step 2

Plot each graph on the same coordinate system.

$(x, y) = (- 2, - 5)$

$x = 3$
