Determine the distance between point $(x1,y1)$ and point $(x_2,y_2),$ and assign the result to pointsDistance. The calculation is:

Distance $=\sqrt[\phantom{2}]{(x^2-x_1{)}^2+(y^2-y_1{)}^2}$

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