1. COORDINATE PLANE x-axisy-axis

2. COORDINATE PLANE QUADRANTS III III IV (+, +)(-, +) (-, -)(+, -)

3. GRAPHING Coordinates of point A is (-2, 4) A

4. Points in the coordinate plane are named by ordered pairs of the form (x, y) The first number, or x-coordinate, corresponds to the numbers on the x-axis. THE COORDINATE PLANE The second number, or y-coordinate, corresponds to the numbers on the y-axis.

5. COORDINATE PLANE NAME THESE POINTS (2, 4) A

6. COORDINATE PLANE NAME THESE POINTS (-1, -2) B

7. COORDINATE PLANE NAME THESE POINTS (-4, 0) C

8. COORDINATE PLANE NAME THESE POINTS (0, 3) D

9. A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping

10. A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping {(2, 3), (-5, 2), (3, 3)}

11. A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping x321 y5-40

12. A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping

13. A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping y = 2x - 3

14. A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping x y 3 5 2 7

15. Recall from Chapter 1, that in a relation… The DOMAIN is the set of all first numbers of the ordered pairs. The RANGE is the set of all second numbers of the ordered pairs. RELATIONS

16. For the relation {(2, 5), (4, -2), (4, 0)} The DOMAIN is {2, 4} The RANGE is {-2, 0, 5} RELATIONS Do not repeat elements in a set. Write sets in numerical order

17. RELATIONS An INVERSE RELATION is obtained by switching the coordinates of each ordered pair. The inverse of {(5, 3), (6, -2), (5, 5)} is {(3, 5), (-2, 6), (5, 5)}

18. RELATIONS Change the following to a mapping: {(5, 3), (6, -2), (5, 5)} x y 5 6 -2 3 5
