Q(4, 2) 2. V(3, 7) 3. T(0, 3) 4. B(8, 6) 5. R(5, 0) 6. L(4, 4) Write the ordered pair that names each point. 7. J (4, 1) 8. X (0, 7) 9. R (2, 2) 10. B (8, 5) 11. K (3, 4) 12. H (8, 0) 13. D (1, 6) 14. N (7, 3) Express each relation as a table and as a graph. Then determine the domain and range. 15. {(3, 5), (1, 3), (5, 1), (2, 4)} 16. {(0, 2), (4, 6), (3, 7)} x y 3 5 1 3 5 1 2 4 x y O 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 x y 0 2 4 6 3 7 x y O 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 domain = {1, 2, 3, 5} domain = {0, 3, 4} range = {1, 3, 4, 5} range = {2, 6, 7} 17. Graph (2, 1), (2, 4), and (5, 1) on the coordinate system. a. Connect the points with line segments. What figure is formed? a triangle b. Multiply each number in the set of ordered pairs by 2. Graph and connect the new ordered pairs. What figure is formed? a triangle c. Compare the two figures you drew. Write a sentence that tells how the figures are the same and how they are different. Sample answer: Both figures are triangles, but one is twice as large as the other.
