Answer
Graph:
Work Step by Step
Intercepts (set x=0, find the y; set y=0, find the x:
$\left[\begin{array}{lll}
x=0, & & y=0\\
6(0)-3y=15 & & 6x-3(0)=15 \\
-3y=15 & & 6x=15\\
y=-5 & & x=2.5\\
(0,-5) & & (2.5,0)
\end{array}\right] $
Checkpoint (select any x, find the accompanying y):
$\left[\begin{array}{l}
x=4\\
6(4)-3y=15 \\
-3y=-9\\
y=3\\
(4,3)
\end{array}\right]$
Plot the points and a line that passes through them
