Mark against the correct answer in each of the following:
The line meets the plane 2x + 3y – z = 14 in the point
Given: Line meets plane 2x + 3y – z = 14
To find: Point of intersection of line and plane.
Explanation:
Let the equation of the line be
Therefore, any point on the line is (2λ + 1, 4λ +2, -3λ +3)
Since this point also lies on the plane,
2(2λ + 1) + 3(4λ +2) – (-3λ +3) =14
4λ + 2 + 12λ + 6 + 3λ – 3 = 14
19λ + 5 = 14
Therefore the required point is (3, 5, 7).
