Pre-Algebra Examples

$x = 7$

Step 1

Since $x = 7$ is a vertical line, there is no y-intercept and the slope is undefined.

Slope: Undefined

y-intercept: No y-intercept

Step 2

Find two points on the line.

$\begin{array}{c} x & y \\ 7 & 0 \\ 7 & 1 \end{array}$

Step 3

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

Slope: Undefined

y-intercept: No y-intercept

$\begin{array}{c} x & y \\ 7 & 0 \\ 7 & 1 \end{array}$
