Question
1. Determine the exact value(s) of k for which the planes x– 2y + kz + 7= 0 and x– 2y – 2 = 0 have an angle of
intersection of 45°?
2. The plane with equation: † = (0,1, –4) + s(2,3,0) + t(1, –1,–5), s, t e R, intersects the x-axis at -2 and the y-axis at
an unknown point A. Determine the equation of the line that contains these two points.
