By observing the given number line, state which of the following statements is true
a. B is 2
b. A is -4
c. B is -13
d. B is -4

Solution:

If we observe carefully the given number line each division on the number line is 1 unit apart. Let us first observe the position of point B. It is 4 units from the left of zero. Similarly the point A is 7 units from the right of zero.

Therefore, the statement B is 2 is a false statement according to the given number line. Similarly, A is -4 is a false statement according to the given number line and also B is -13 again a false statement. The correct statement is B is -4.

✦ Try This: Can you try locating point C on a number line given the conditions:

1. a) Point C is 8 units away from the left of zero.
2. b) Point C is 9 units away from the right of zero.
