Mark a dot on 2 on the y axis. From there you should have the point (0,2). Once doing that, rise up 2 squares, then go left once. That should lead you to (-1,4). Not only do you have to go back upwards but you have to go forward downwards. Starting from (0,2) again go down 2 squares and over to the right landing on (1,0) . You the continue that pattern. After you think you’ve done enough marks you make a straight line through all of them, then making your slope
