Work Step by Step

Divide both sides with 3, $y=\displaystyle \frac{4}{3}$ can be written in the form $y=mx+b$ as $y=0\displaystyle \cdot x+\frac{4}{3}.$ From here, we read: slope =0, y-intercept=$\displaystyle \frac{4}{3}$ 1. Plot the point $(0,\displaystyle \frac{4}{3})$. 2. Slope zero means zero rise ($m=\displaystyle \frac{\Delta y}{\Delta x} =\displaystyle \frac{Rise}{Run}$) meaning that the line is horizontal (parallel to the x-axis), and it passes through $(0,\displaystyle \frac{4}{3})$. This is enough information to graph the line.
