Find the distance between the pair of points. Give an exact answer and where appropriate an approximation to three decimal points.
(-4,-7) and (-1,3)
=======================
distance = sqrt[(3--7)^2 + (-1--4)^2]
distance = sqrt[10^2 + 3^2]
distance = sqrt[109]

The distance between two given points (,) and (,) is given by . Just plug in your coordinate values and do the arithmetic.

Unless you end up with a perfect square (and you won't if you do the arithmetic correctly), leave the answer in radical form for an exact answer. Punch the radicand into a calculator and take the square root for your decimal approximation, although I would say doing so was inappropriate for this problem.
