Question

What is the distance between the points (10, –7) and (10, 9) on the coordinate plane?

Answer 1

The distance between (10,-7) and (10,9) is 16 square units because -7 in absolute value + 9 in absolute value is 16 square units

Answer 2

Distance= sqrt((10-10)^2+(9-(-7))^2) =sqrt((0)+(16)^2) =sqrt(256) =16
