Consider the following figure.

Question

A number line with point A at negative 2, point B at negative 1, point C at 1, point D at 3, point F at 4.5, and point G at 6.

Find AD, CG, and BD.

Enter your answer as three numbers.

Separate the numbers by commas, like this: 42, 53, 64
I'm confused with this

Answer 1

AD is the distance between A and D, so
AD = |D-A| = |3-(-2)| = |5| = 5
and so on
