"Fun with Coordinates"

[discepolo1]

I also need some help with a program that takes two points given by the user and outputs the following:

what quadrant or axes they are located
calculates and displays the lines euclidean (sqrt((Xp-Xq)^2 + (Yp-Yq)^2)) and manhattan ((abs(Xp-Xq)) + (abs(Yp-Yq)))distance
calculates the slope and y-intercept.

if someone could help explain to me how to do this that would be great! thanks
