Work Step by Step
Find the intercepts (set x=0, set y=0)
and a check point (set a value for x, find y)
$\left[\begin{array}{lll}
\text {y-intercept } & \text {x-intercept} & \text {checkpoint}\\
& & \\
x=0 & y=0 & x=3\\
0+3y=6 & x+0=6 & 3+3y=6\\
y=2 & x=6 & 3y=3\\
& & y=1\\
(0,2) & (6,0) & (3,1)
\end{array}\right]$
Plot the points and a line through them.
