Solved Example on Relation

Ques: Choose a graph that represents the relation {(3, - 4), (5, - 4), (- 6, - 4), (2, 3)}.

    Choices:
    A. Graph 3
    B. Graph 1
    C. Graph 4
    D. Graph 2
    Correct Answer: D

Solution:

    Step 1: Graph each ordered pair on a coordinate plane
    Step 2: The graph that represents the relation {(3, - 4), (5, - 4), (- 6, - 4), (2, 3)} is Graph 2
