Step 1.1.1

Subtract $2$ from both sides of the equation.

$- 3 x = 5 - 2$

Step 1.1.2

Subtract $2$ from $5$ .

$- 3 x = 3$

Step 1.2

Divide each term in $- 3 x = 3$ by $- 3$ and simplify.

Step 1.2.1

Divide each term in $- 3 x = 3$ by $- 3$ .

$\frac{- 3 x}{- 3} = \frac{3}{- 3}$

Step 1.2.2.1.1

Cancel the common factor.

$\frac{- 3 x}{- 3} = \frac{3}{- 3}$

Step 1.2.2.1.2

Divide $x$ by $1$ .

$x = \frac{3}{- 3}$

Step 1.2.3

Simplify the right side.

Step 1.2.3.1

Divide $3$ by $- 3$ .

$x = - 1$

Step 2

Since $x = - 1$ 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.

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

Step 4

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

Slope: Undefined

y-intercept: No y-intercept

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