Question

Which of the following is the distance between the two points shown?

A graph with the x-axis starting at negative 4, with tick marks every one-half unit up to 4. The y-axis starts at negative 4, with tick marks every one-half unit up to 4. A point is plotted at negative 2.5, 0 and at 1.5, 0.

−4 units
−1.5 units
1.5 units
4 units

Answer 1

The distance between the two points (-2.5, 0) and (1.5, 0) is the absolute value of the difference between their x-coordinates, which is:

|1.5 - (-2.5)| = 4

Therefore, the distance between the two points is 4 units.
