1. The problem statement, all variables and given/known data I am given the equation of two lines that are in three space. They are in the form of (X=, Y=, Z= ). The questions wants me to prove whether or not the lines intersect. 2. Relevant equations The equations of the lines. It gives me just the points in the equation, but it is assumed I can get the equation of the line easily. 3. The attempt at a solution I guess I need to find a common point some how? I know the intersections may not be at the same time.
