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.
