Mark against the correct answer in each of the following:
The point of intersection of the line and the plane 2x – y + 3z – 1 = 0, is
Given: Line meets plane 2x – y + 3z – 1 = 0
To find: Point of intersection of line and plane.
Explanation:
Let the equation of the line be
Therefore, any point on the line is (3λ + 1, 4λ - 2, -2λ + 3)
Since this point also lies on the plane,
2(3λ + 1) - (4λ -2) + 3(-2λ +3) = 1
6λ + 2 – 4λ + 2 – 6λ + 9 = 1
-4λ = -12
λ = 3
Therefore required point is (10, 10, -3)
