Work Step by Step
Find the intercepts (set x=0, set y=0)
and a check point (set a value for x, find y)
$\left[\begin{array}{lll}
\text {y-intercept } & \text {x-intercept} & \text {checkpoint}\\
& & \\
x=0 & y=0 & x=1\\
0-2y=12 & 6x-0=12 & 6(1)-2y=12\\
y=-6 & x=2 & -2y=6\\
& & y=-3\\
(0,-6) & (2,0) & (1,-3)
\end{array}\right]$
Plot the points and a line through them.
