Step 1

1 of 4**Find a few points on the first line.**
First, express y by subtracting x from both sides.

$x+2y-(x)=4-(x)$

$2y=4-x$

Then, divide by 2.

$y=2-\frac{1}{2}x$

Choose a few x-points and include them back to the equation to solve for y. → $\quad\text{for}\quad x=0 \quad\quad\text{ }\text{ }\ y=2$ → $\quad\text{for}\quad x=4 \quad\quad\text{ }\text{ }\ y=0$
