For the first one you mark your first point at 0 and count up 2 and go to the right 3 and mark ur next point and again count up 2 and go to the right 3 times. And then go back to 0 and count down 2 and go to the left 3 times and repeat. For the second one it’s the same thing, mark ur first point at 0, and since the slope is negative you count up 2 and go to the left 1 time and mark ur next point and repeat. To complete the bottom you go back to 0 and count down 2 and go to the right 1 time and repeat. Hopefully this helps!
