...python programming? Write a python program to accept inputs from the user which are two lines in the form:
y=(m1)x+b1
y=(m2)x+b2
The user inputs the numbers m1,b1,m2,b2
then the program calculates the intersection of twolines and print the intersection coordinate.

You would do it just like you would algebraically.

First, look at the two slopes provided. If they're different, we're fine. (If they're the same, then there is no unique solution.)

To find the intersection, we need to find the point where
(m1)x+b1 = (m2)x+b2
so
(m1-m2)x = b2-b1
x = (b2-b1) / (m1-m2)

Plugging the found x value into either equation will yield the y coordinate of the intersection point.

Here's Python code (Indents indicated by __):
class NoUniqueSolutionError: pass


class Intersection:
__ def __init__(self, m1, b1, m2, b2):
____ if m1 == m2:
______ raise NoUniqueSolutionError()
____ self.inputs = [m1,b1,m2,b2]
____ self.x = x = (b2-b1)/(1.0*m1-m2)
____ self.y = m1*x+b1

i=Intersection(1,0,-1,5)
print i.x, i.y
