1. The problem statement, all variables and given/known data The plane that passes through the point (−3, 2, 1) and contains the line of intersection of the planes x + y − z = 3 and 4x − y + 5z = 5 2. Relevant equations 3. The attempt at a solution So I plugged the planes into a matrix and found the line of intersection with one parameter. I took the coefficients as the direction vector of the line. Plugging that into an equation of the plane, I get the following: (5/6)X-(19/5)Y+(56/5)Z but it says I'm wrong. I only have 1 attempt left at the right solution.. Please help! Thanks in advance!
