Calculate the distance between the points N=(-2,-1) and L=(3-4) in the coordinate plane. Give an exact answer (not a decimal approximation)

Answer 1

The distance in the x direction is (-2 -3) units = -5 units

The distance in the y direction is ([-1 - (-4)] units = 3 units

The hypotenuse is sqrt(25+9) = sqrt(34).

There is no way to give this as an "exact" answer since 34 is not a perfect square.
