$1\mathrm{.}28\mathrm{.}3$: Using math functions to calculate the distance between two points.

Determine the distance between point $($x$1,$ y$1)$ and point $($x$2,$ y$2),$ and assign the result to pointsDistance. The calculation is:

Ex: For points $(1\mathrm{.}0,2\mathrm{.}0)$ and $(1\mathrm{.}0,5\mathrm{.}0),$ pointsDistance is $3\mathrm{.}0.$
