Hey! so I'm taking Multivariable Calculus and I'm really confused about this problem... Line A lies in the xyplane and bisects its 1st and 3rd quadrants. Line B lies in the zxplane and bisects its 1st and 3rd quadrants. Find the equation of the plane determined by these two lines.

Create expressions for lines A and B. Compute the cross product (of A and B) C. The plane you want is perpendicular to C and passes through the origin.
