Answer
Refer to the graph below.
Work Step by Step
Solve for $y$ by adding $y$ to both sides:
$5x-y+y=0+y
\\5x=y
\\y=5x$
Thus, the given equation is equivalent to $y=5x$.
To graph the equation, perform the following steps:
(1) Create a table of values by assigning convenient values to $x$, then solve for the corresponding value of $y$ for each value of $x$.
(refer to the attached image below for the table)
(2) Plot each point (or ordered pair) on the same coordinate plane, then connect the points using a straight line.
