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

Determine the distance between point $(x1,y1)$ and point $(x2,y2),$ and assign the result to pointsDistance. The calculation is:

Distance $=\sqrt[\phantom{2}]{(x2-x1{)}^2+(y2-y1{)}^2}$

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