$8 = x + 3$

Step 1

Solve for $y$ .

Step 1.1

Since $x$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$x + 3 = 8$

Step 1.2

Move all terms not containing $x$ to the right side of the equation.

Step 1.2.1

Subtract $3$ from both sides of the equation.

$x = 8 - 3$

Step 1.2.2

Subtract $3$ from $8$ .

$x = 5$

Step 2

Since $x = 5$ 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.

$\begin{array}{c} x & y \\ 5 & 0 \\ 5 & 1 \end{array}$

Step 4

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

Slope: Undefined

y-intercept: No y-intercept

$\begin{array}{c} x & y \\ 5 & 0 \\ 5 & 1 \end{array}$
