Solve for $x$ by subtracting $x$ to both sides of the equation: $x+y-x=4-x \\y=-x+4$ Thus, the given equation is equivalent to $y=-x+4$. 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. (refer to the attached image in the answer part above for the final graph)
