Your table has two columns. The first column represents the x values, and the second column represents the y values.
1) Group each pair to form (x, y) pairs. (0, 2) (2, 4) (4, 8)
2) Graph each ordered pair on the coordinate plane. X-coordinate determines direction right or left, and y-coordinate deterines direction up or down. For example, to graph (0, 2) begin at center - origin- where x axis and y axis meet and do not go left or right then go up 2. Similarly, for (2, 4) start at the origin and move right 2 and up 4.
3) After all ordered pairs are graphed use a ruler or other straight edge to connect the points.
