Slope Finder

[nevets04]

I just put this together quickly for homework for my algerbra 1 class.
I had about 54 problems that I had to do something like find he slope for a line that goes through (4,2) and (3,2)
This program easily solves that prblem, i finished my homework in a couple of minutes

Code:

import os
os.system("clear")
while True:
    print "--------------------------------------------------"
    print "        Slope Finder             "
    print "--------------------------------------------------"
    a = 0
    b = 0
    c = 0
    d = c
    a = input("First x: ")
    b = input("First y: ")
    c = input("Second x: ")
    d = input("Second y: ")
    print d - b,"/",c - a
