Step 2.1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 2.2

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m = 0$

$b = \frac{4}{3}$

Step 2.3

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $0$

y-intercept: $(0, \frac{4}{3})$

Slope: $0$

y-intercept: $(0, \frac{4}{3})$

Step 3

Find two points on the line.

$\begin{array}{c} x & y \\ 0 & \frac{4}{3} \\ 1 & \frac{4}{3} \end{array}$

Step 4

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

Slope: $0$

y-intercept: $(0, \frac{4}{3})$

$\begin{array}{c} x & y \\ 0 & \frac{4}{3} \\ 1 & \frac{4}{3} \end{array}$
