# Thread: Determine if a line intersects a plane where 2 points for line, 3 points for plane

1. ## Determine if a line intersects a plane where 2 points for line, 3 points for plane

Hi, how can I determine if a line(given (x1,y1,z1),(x2,y2,z2) on the line) intersects a plane(given (x3,y3,z3),(x4,y4,z4), (x5,y5,z5) on the plane)

Thanks helping.

3. While it's not hard, if you don't know cross products, dot products and parametric equations of lines, it's a long lecture.
