1. The problem statement, all variables and given/known data Consider the intersection between the following two planes given in parametric form: P1 : x = [2, 4. 3] + s1[1, 2, 1] + s2[2, 5, 4] P2 : x = [1, 0, -5] + t1[3, 8, 7] + t2[2, 1, -5] Find the intersection of the two planes as a line in parametric form. 2. Relevant equations 3. The attempt at a solution I don't understand how to approach this question at all. At first I thought just to approach it as a system of linear equations and leave one variable as free. But it went nowhere for me.
