/* YOUR PROGRAM ASSUMES THAT THE SLOPES AND Y-INTERCEPTS ARE INTEGERS
  * EVEN IF THEY WERE INTEGERS, THE COORDINATES OF THE POINT OF INTERSECTION ARE NOT NECESSARILY INTEGERS
  * ALTHOUGH YOUR COORDINATES ARE DOULBES, THEY ARE CALCULATED FROM INTEGER.
  * THEREFORE THEY ARE INTEGERS CAST INTO DOUBLES. THE DECIMAL PART IS DISCARDED
  * SO YOUR ANSWER IS WRONG IF THE COORDINATES OF THE SOLUTION ARE NOT INTEGERS
  *
  * YOUR CODE IS HARD TO READ BECAUSE THERE ARE NO COMMENTS, ALMOST NO INDENTING, AND NO USE OF BRACES FOR if CODE
