I have tried to solve this problem for a while now, and I always seem to get the wrong answer. I really need help.
Two points form a line. How do I find the the x and y coordinates of a point that is n units from one point going towards the other point along the line?
A B C
How do you find where B is? I turn the line into a triangle and use similar edges of it to find the answer. However, this do what I need; I want to use some sort of equation/rule to find the location of B.
