    ok how dose that help me solve this problem

    Do the table first. Make one column x, and the other column y. Pick a few integers, centered around 0 (such as -3,-2,-1,0,1,2,3), and put them under x. Then, use your equation to find the corresponding y values.

    Draw a set of axes, and label them x and y. Number them, with a scale that makes sense. Now, put each of the points you found in the table on the graph.

    I'm being a little more generous than people here usually are, as you seem to be really new at this. However, you are usually expected to show some attempt at solving your own work.
