If you would like to see a graph, first you must have an equation. For example, the equation y=x. To plot a graph of this equation, you must make a "table" of values. Choose 5 x values and solve for the y values. Then "plot" them on the graph. Draw a line straight up and a line straight across, and put "notches" on them that are equally spaced apart. Label the notches as 1,2,3,4,5 on the right side, and -1,-2,-3,-4,-5 on the left side. Label it 1,2,3,4,5 on the vertical part as it goes up, and label -1,-2,-3,-4,-5 on the vertical part as you go down. The horizontal line is the x coordinate and the vertical is the y coordinate.

For the equation y=x, if you choose x=1, then y=1 too. If x=2, then y=2 as well. These two solutions are called "points." All points have an x and a y value and are written like this: (1,1), (2,2). To plot (1,1) on the graph, go 1 notch to the right and 1 notch up, then put a dot there. (1,1) means go 1 right and 1 up. (2,2) means go 2 right and 2 up. (-2,-2) means go left 2 and down 2.
