# What is the distance between (-73,-22) and (-61,-14)?

Use the distance formula $d = \sqrt{{\left({x}_{2} - {x}_{1}\right)}^{2} + {\left({y}_{2} - {y}_{1}\right)}^{2}}$ for (${x}_{1} , {y}_{1}$) and (${x}_{2} , {y}_{2}$)
This is really just another form of Pythagorus' Theorem: $c = \sqrt{{a}^{2} + {b}^{2}}$
