Question

The distance between the points A (0, 6) and B (0, –2) is

A:8

B:6

C:2

D:4

Answer

By using the distance formula:

d2 = (x2 - x1)2 + (y2 - y1)2

Lets calculate the distance between the points (x1, y1) and (x2, y2)

We have;

x1 = 0, x2 = 0

y1 = 6, y2 = - 2

d2 = (0 – 0)2 + ( - 2 – 6)2

d =

d =

d = 8 units

So, the distance between A (0, 6) and B (0, 2) = 8
