#### Answer

Refer to the image below for the graph.

#### Work Step by Step

Write the equation in $y=mx+b$ form by solving for $y$ to obtain:
$\dfrac{x}{4} + \dfrac{y}{5}=0
\\20\left(\dfrac{x}{4} + \dfrac{y}{5}\right) = 20(0)
\\5x+4y=0
\\4y = 0-5x
\\4y=-5x$
Divide $4$ to both sides of the equation to obtain:
$\dfrac{4y}{4}=\dfrac{-5x}{4}
\\y=-\dfrac{5}{4}x$
To graph the given equation, perform the following steps:
(1) Create a table of values by assigning values to $x$ then solving for the corresponding value of $y$ for each one.
(refer to the attached image below)
(2) Plot each point from the table of values, then connect the points using a line to complete the graph.
