The above applet is designed to find the intersection point between two lines specified by the user.
The two lines are as follows:
y = m1*x + b1 shown in red and
y = m2*x + b2 shown in green.
In order to change the values for m1, m2, b1, or b2, merely click in the text field and type a number.
The point of intersection is shown at the top of the graph and displayed as a blue point.
If there is no point of intersection or infinitely many, the program will tell you.
