Assertion : A point on the straight line `2x + 3y- 4z = 5` and `3x - 2y + 4z = 7` can be determined by taking `x = k` and then solving the two equations for `y` and `z`, where k is any real number

Reason : If `c' ne kc`, then the straight line `ax + by + cz + d = 0, kax + kby + c'z + d' = 0`, does intersect the plane `z = alpha`, where `< alpha` is any real number.
