Question

Find the distance between the points (2, 3) and (2, 8).

Answer 1

You use the distnace formula which is square root of (x2 - x1)^2 + (y2 - y1)^2.
In this case:
 
square root (2-2) ^2 + (8 - 3)^2
square root of (0)^2 + (5)^2
square root of 25 = 5 

So the distance is 5

Answer 2

The answer would be 5.
