Two real numbers have coordinates w and t as shown on the number line below. Copy the number line into your Student Answer Booklet W + 2 3 -5 -4 3 2 1 0 1 4 5 a. What are the two real numbers represented by w and t on the number line? b. The coordinate of Point A on the number line is w + t. Plot and label Point A on the number line and explain how you decided upon its location. c. The coordinate of Point B on the number line is w — t. Plot and label Point B on the number line and explain how you decided upon its location, . d. The coordinate of Point C on the number line is wet. Plot and label Point C on the number line and explain how you decided upon its location.

The location of w and t on the number line arenot exact so you will need to approximate .

In the first point w, it is between -4 and - 3 but closer than -4 compared to -3.Additionally, the point w is located at a position greater than -3.5 .It will be okay to approximate point w at -3.6.

w= -3.6

In the second point t, it is located between 0 and 1 but closer to 0 than 1. Additionally, t is less than 0.5 because it is located at a position less than 0.5, hence it is approximately at : t = 0.4

w= -3.6 and t = 0.4 -------approximated actual values

The two real numbers for w and t will be :

w= - 4 and t = 0 ---------approximated real numbers.

NB;

w= -3.7 and t= 0.3 is also a correct approximate because the difference of +/- 0.1 can be allowed for this case.
