Two lines with boundary points are given . i need to find intersection point between these lines (after extrapolating them ) without the use of skope and intercept

What does "extrapolating them" mean? What is "skope" and "intercept"?

What do you mean when you say you can't use slope and intercept? What prevents you from doing that? For a general pair of lines, there is no way to compute their intersection without deriving the equations for the lines.

You might think this avoids slope and intercept, but it doesn't.
p1=[100;107.5;1];
p2=[100;17.5;1];
p3=[12.5;110;1];
p4=[102.5;110;1];
P=cross( cross(p1,p2) , cross(p3,p4) );
P=P(1:2)/P(3) %intersection point
