Answer
Refer to the graph below.
Work Step by Step
Solve for $y$.
Subtract $4x$ to both sides:
$4x-5y-4x=20-4x
\\-5y=-4x+20$
Divide both sides by $-5$:
$\dfrac{-5y}{-5}=\dfrac{-4x+20}{-5}
\\y=\dfrac{4}{5}x-4$
This means that the given equation is equivalent to $y=\frac{4}{5}x-4$.
To graph the equation, perform the following steps:
(1) Create a table of values by assigning $-5, 0,$ and $5$ to $x$ then solving for the corresponding value of $y$ of each one.
(refer to the attached image below for the table)
(2) Plot each point and connect them using a line.
