x - 4 = 0

$x - 4 = 0$

Step 1

Add

4

$4$ to both sides of the equation.

x = 4

$x = 4$

Step 2

Since

x = 4

$x = 4$ 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{matrix} x & y 4 & 0 4 & 1 \end{matrix}

$\begin{array}{c} x & y \\ 4 & 0 \\ 4 & 1 \end{array}$

Step 4

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

Slope: Undefined

y-intercept: No y-intercept

\begin{matrix} x & y 4 & 0 4 & 1 \end{matrix}

$\begin{array}{c} x & y \\ 4 & 0 \\ 4 & 1 \end{array}$
