How do you graph y-x equals 4?

Answer 1

In order to graph y-x = 4, consider three things. First, the equation is linear. You know this because the exponents on the y and x terms are no greater than 1, so the equation describes a straight line. Second, solve for y = 0. This gives you (x,y) = (-4,0). Third, solve for x = 0. This gives you (x,y) = (0,4).

Now, plot the two points (-4,0) and (0,4). Draw a straight line between them, extending beyond them (essentially) to infinity. You are done.
