    There are an infinite number of coordinates. Literally.

    To graph, you technically only need two coordinates. I like doing the intercepts but you may be required to do more than that for class.

    Basic concept is the pick a number of your choosing for x, plug it in, and then solve for y. That set is your coordinates. Then choose another number for x and repeat. It's common to start with 0 for the x, then do like 1 and -1, and 2 and -2, that type of thing.

    For instance, if x = 0, then y is going to equal -4. So the coordinate is (0, -4).

    Graph each inequality
    y<2x +2

    y< 2x+2
    y=2x+2
    4=2x+2
    -2= 2x-2
    2=2x
    x=1
