Answer
Refer to the image below for the graph.
Work Step by Step
Write the equation in $y=mx+b$ by isolating $y$ on one side of the equation:
\begin{array}{ccc}
&x&=&\frac{5}{4}y
\\&\frac{4}{5} \cdot x&=&\frac{4}{5} \cdot \frac{5}{4}y
\\&\frac{4}{5}x&=&y
\\&y &=&\frac{4}{5}x
\end{array}
The given equation has:
slope = $\dfrac{4}{5}\\$
y-intercept = $0$
To graph the equation, perform the following steps:
(1) Plot the y-intercept point $(0, 0)$.
(2) From $(0, 0)$, use the slope to locate another point.
Move 4 units up (the rise) and 5 units to the right (the run) to end at the point $(5, 4)$.
(3) Connect the two points using a straight line to complete the graph.
