Work Step by Step
Find the intercepts (set x=0, set y=0)
and a check point (set a value for x, find y)
$\left[\begin{array}{lll}
\text {y-intercept } & \text {x-intercept} & \text {checkpoint}\\
& & \\
x=0 & y=0 & x=7\\
0-y=7 & 2x-0=7 & 2(7)-y=7\\
y=-7 & x=7/2 & -y=-7\\
& & y=7\\
(0,-7) & (3.5,0) & (7,7)
\end{array}\right]$
Plot the points and a line through them.
