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

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
