The plane 5x + y + kz + 1 = 0 and directional ratios of a line (3, -1, 1) are parallel, find k.
The plane 5x + y + kz + 1 = 0 and directional ratios of a line (3, -1, 1) are parallel, find k. Correct Answer -14
The condition for a plane and a line are parallel to each other is a1a + b1b + c1c = 0. 5(3) + 1(-1) + k(1) = 0 K(1) = -14 K = -14
