Question

What is the number of units between Point A and Point B?

A coordinate plane with two points. Point A has coordinates 2 comma 1 and point B has coordinates 5 comma 5.

Answer 1

To find the number of units between Point A and Point B, we can use the distance formula in geometry:

Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

In this case, Point A has coordinates (2,1) and Point B has coordinates (5,5).

Distance = sqrt((5-2)^2 + (5-1)^2)
Distance = sqrt(3^2 + 4^2)
Distance = sqrt(9 + 16)
Distance = sqrt(25)
Distance = 5

Therefore, the number of units between Point A and Point B is 5.
