The Distance Formula Program is a simple program for the TI-84 Plus CE calculator that allows you to calculate the distance between two points in the XY plane.
All you have to do is enter the coordinates of the two points for which you would like to find the distance between. For example, to find the distance between (7,8) and (3,5), you would enter 7 as X1, 8 as Y1, 3 as X2, and 5 as Y2. The program would then return your answer, which would be 5 in this case.
