Question

How do you graph `2x-y=9`?

Answer 1

You can either construct a table of values OR:
1. Arrange the equation:
`y=2x-9`
From this you know the y-intercept is -9, and also for every one point you move to the right it goes 2 points up.
So your points would look something like this:
(0, -9) (1, -7) (2, -5) and so on, and would also stretch beyond the y-axis.
