Answer
Refer to the graph below.
Work Step by Step
Solve for $y$.
Subtract $x$ to both sides of the equation:
$x+2y-x=8-x
\\2y=8-x$
Divide $2$ to both sides of the equation:
$\frac{2y}{2}=\frac{8-x}{2}
\\y=\frac{8}{2} -\frac{x}{2}
\\y=4-\frac{x}{2}
\\y=-\frac{x}{2}+4$
Thus, the given equation is equivalent to $y=-\frac{x}{2}+4$.
To graph the equation, perform the following steps:
(1) Create a table of values by assigning convenient values to $x$, then solve for the corresponding value of $y$ for each value of $x$.
(refer to the attached image below for the table)
(2) Plot each point (or ordered pair) on the same coordinate plane, then connect the points using a straight line.
