Points P and Q are at the following locations on a number line:
- P is at -8.
- Q is at -3.

Which number is on PQ but not on QP?
A. -10
B. -5
C. -1
D. Every number on PQ is also on QP

Answer :

The number that is on PQ but not on QP based on the information about the number line is -5.

How to explain the number line

Based on the information, the segment PQ is the set of numbers that are between -8 and -3 on the number line, including -8 but not including -3. So we have:

PQ: -8, -7, -6, -5

The segment QP is the set of numbers that are between -3 and -8 on the number line, including -3 but not including -8. So we have:

QP: -3, -4, -5, -6, -7

The number -5 appears in PQ but not in QP. Therefore, the answer is -5.

The numbers on PQ but not on QP are -7 and -6. Hence the correct option is c.

To find the number that is on PQ but not on QP, we need to identify the numbers between -8 and -3.

The numbers between -8 and -3 are -7, -6, and -5.

Now, let's consider the number line representation of PQ and QP:

PQ: -8 -7 -6 -5 -3

QP: -3 -5 -6 -7 -8

From the comparison, we can see that -7 and -6 are on PQ but not on QP.

So, the answer is:

The numbers on PQ but not on QP are -7 and -6. Hence the correct option is c.
