Chapter 1 Graphs, Functions, and Models Exercise Set 1.1 1. Point A is located 5 units to the left of the y-axis and 4 units up from the x-axis, so its coordinates are (−5, 4). Point B is located 2 units to the right of the y-axis and 2 units down from the x-axis, so its coordinates are (2, −2). Point Cis 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). 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). 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 (−5, −4). Point F is located 3 units to the right of the y-axis and 0 units up or down from the x-axis, so its coordinates are (3, 0). 2. G: (2, 1); H: (0, 0); I: (4, −3); J: (−4, 0); K: (−2, 3); L: (0, 5) 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 left of the y-axis. Then we move 5 units down from the x-axis. To graph (−1, 4) we move from the origin 1 unit to the left of the y-axis. Then we move 4 units up from the x-axis. To graph (0, 2) we do not move to the right or the left of the y-axis since the first coordinate is 0. From the origin we move 2 units up. To graph (2, −2) we move from the origin 2 units to the right of the y-axis. Then we move 2 units down from the x-axis. 4. 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. 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. To graph (2, 3) we move from the origin 2 units to the right of the y-axis. Then we move 3 units up from the x-axis. To graph (2, −1) we move from the origin 2 units to the right of the y-axis. Then we move 1 unit down from the x-axis. To graph (0, 1) we do not move to the right or the left of the y-axis since the first coordinate is 0. From the origin we move 1 unit up
