Question

Identify the points corresponding to p and q. Help needed!!

A.P’(4,3),Q’(2,7)
B.P’(5,4),Q’(2,7)
C.P’(5,4),Q’(8,7)
D.P’(3,4),Q’(6,7)

Answer 1

The points corresponding to P=(3,4) and Q=(6,7), so the answer is D.

Explanation:

Ok, in mathematics, given two sets X and Y, the collection of all the ordered pairs (X, Y), formed with a first element in X and a second element in Y, is called the Cartesian product of X and Y. The Cartesian product of sets allows define relationships and functions. In this case, it is a function that contains two points, denoted P and Q. Given, the ordered pair of each, first read the one corresponding to the X axis and then to the Y axis.

For P: you read X and you see that it is on 3 (between 2 and 4), and then the Y axis is on 4 (between 3 and 5).

For Q: you read X and you see that it is on 6 (between 5 and 7) and then the Y axis is on 7 (between 6 and 8)
