Question

For which pair of points can you use this number line to find the distance?

a) (0, 3) and (3, 0)
b) (1, 0) and (-1, 3)
c) (2, 0) and (2, 3)
d) (-1, 0) and (-1, -3)

Answer 1

To find the distance between two points on a number line, subtract the smaller value from the larger value.

Step-by-step explanation:

To find the distance between two points on a number line, subtract the smaller value from the larger value.

a) Distance = |3-0| = 3 units

b) Distance = |-1-1| = |-2| = 2 units

c) Distance = |2-2| = 0 units

d) Distance = |-3-(-1)| = |-3+1| = |-2| = 2 units
