First, find the x-intercept. Let y=0,
−x+2y=6−x+2(0)=6−x=6x=−6
The x-intercept is (−6,0).
Now find the y-intercept. Let x=0.
−x+2y=6−0+2y=62y=6y=3
The y-intercept is (0,3).
Find a third point. We’ll use x=2,
−x+2y=6−2+2y=62y=8y=4
A third solution to the equation is (2,4).
Summarize the three points in a table and then plot them on a graph.

Do the points line up? Yes, so draw line through the points.
