    x1 = -2+2t <-- put these values in the plane and find the value of t.

    Okay, I got t=13/38. So plugging that back into my line equation, I get the point <-25/19,75/38,65/38>.

    well ... put those point on the plane and check if it's correct or not.

    @experimentX Could you do work out this problem and do a quick check of the values? I followed your instructions but when I plug them back in to the line equation and the plane equation, I don't get the same position vector....
