Go up 7 on the coordinate plane (up 7 on the y-axis). Go left 2 on the x-axis. Draw a dot where -2 and 7 meet. That is the point. Assuming you have a grid go up 4 and 1 to the right. Draw a point. Then go back to the first point (-2,7). Go down 4 and 1 to the left. Repeat this as many times as you want. Connect the points and draw the line.
