$x = - 1$

Since $x = - 1$ is a vertical line, there is no y-intercept and the slope is undefined.

Slope: Undefined

y-intercept: No y-intercept

Find two points on the line.

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

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

Slope: Undefined

y-intercept: No y-intercept

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