Question

In the following cases, determine whether the given planes are parallel or perpendicular, and in case they are neither, find the angles between them.

2x – y + 3z – 1 = 0 and 2x – y + 3z + 3 = 0

Answer 1

The equations of the planes are  2x – y + 3z – 1 = 0 and 2x – y + 3z + 3 = 0

Thus, the given lines are parallel to each other.
