Let this point be and

Since C is on the line, we can see that:

Since , then :

Convert a,b, c into terms of lambda and solve for it. Then, plug it in back to the equation of your line to get which should correspond to your point as it originates form the origin. - Jun 7th 2008, 11:47 AMSimplicity
