To find the distance, draw the right triangle for which the line would act as a
hypotenuse.
Next, calculate the length of the horizontal leg by finding the difference in the
x values: 8 – 3 = 5. Do the same for the vertical leg using the difference in the y
values: 14 – 2 = 12. Now plug those two lengths into the good ol’ Pythagorean
Theorem.
The distance is 13.
