Question

Find the distance between the two points in simplest radical form.
(8,-8) and (-1,4)

Answer 1

15 units

Explanation:

As we travel from the 2nd point to the 1st, x increases by 9 units and y decreases by 12 units.

Adapting the distance formula to this situation, we get

√[ (9)^2 + (12)^2 ] = √(81 + 144) = √225 = 15.

The distance between the two points is 15 units.
