Look at the number line below. Choose the TWO expressions that correctly show the distance between the two point

Question

l −3 + 5 l

5 + ( − 3)

5 +l −3 l

5 − ( − 3)

Answer 1

The distance is the difference in the coordinates.

d = 5 - (-3) = 5 + 3 = 8

This is equivalent to

d = 5 + |-3| = 5 + 3 = 8
