Lines and points

The easiest way to find the point of intersection is by solving the two equations with two unknowns.

Or you can do it in the following way:

Two line are given by:

y=a*x+b

y=c*x+d

The point of intersection is then:

(x,y)=(frac{d-b}{a-c},a*frac{d-b}{a-c}+b)

Find the point of intersection between two lines

Line 1: y = ax + b
a: b:
Line 2: y = cx + d
c: d:
