Point C is located 0 units to the right or left of the y-axis
and 5 units down from the x-axis, so its coordinates are
(0, −5). 5. To graph (−5, 1) we move from the origin 5 units to the
left of the y-axis. Then we move 1 unit up from the x-axis.
Point D is located 3 units to the right of the y-axis and

5 units up from the x-axis, so its coordinates are (3, 5). To graph (5, 1) we move from the origin 5 units to the right
of the y-axis. Then we move 1 unit up from the x-axis.
Point E is located 5 units to the left of the y-axis and
4 units down from the x-axis, so its coordinates are To graph (2, 3) we move from the origin 2 units to the right

Point F is located 3 units to the right of the y-axis and To graph (2, −1) we move from the origin 2 units to the
0 units up or down from the x-axis, so its coordinates are right of the y-axis. Then we move 1 unit down from the

L: (0, 5) we move 1 unit up.
3. To graph (4, 0) we move from the origin 4 units to the right

of the y-axis. Since the second coordinate is 0, we do not
move up or down from the x-axis.

To graph (−3, −5) we move from the origin 3 units to the (2, 3)
