Question

Given l(-4,3) and m(-7,-2), what's the length of lm

Answer 1

Distance = Square Root ( (X difference)^2 + (Y difference)^2 )

Distance = Square Root ( (-4 --7)^2 + ( 3 --2)^2 )

Distance = Square Root (3^2 + 5^2)

Distance = Square Root (9 + 25)

Distance = Square Root (34)

Distance = 5.8309518948

Therefore the length of lm equals 5.8309518948
