$x + 2 = 0$

Step 1

Subtract $2$ from both sides of the equation.

$x = - 2$

Step 2

Since $x = - 2$ is a vertical line, there is no y-intercept and the slope is undefined.

Slope: Undefined

y-intercept: No y-intercept

Step 3

Find two points on the line.

$\begin{array}{c} x & y \\ - 2 & 0 \\ - 2 & 1 \end{array}$

Step 4

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

Slope: Undefined

y-intercept: No y-intercept

$\begin{array}{c} x & y \\ - 2 & 0 \\ - 2 & 1 \end{array}$
