1. The problem statement, all variables and given/known data Please disregard, sign error corrected in the cross product Determiner the line of intersection of the following two planes. Write the parametric equations for this line. 2x+y-2z=5 3x-6y-2z=15 2. Relevant equations 3. The attempt at a solution First I crossed my normal vectors from the given equations: (2,1,-2)cross(3,-6,-2)= (-14,-2,15) Then I solved my simultaneous equations starting with y=0, which gave me x=10 and z= (15/2). To get into the parametric equation I took the point (10,0,15/2) + t(-14,-2,15), which gave me x=10-14t y=-2t z=15t+(15/2) Viewing this data in calcplot 3d shows that my line of intersection is no where near my planes.
