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