Q.

Equation of the plane through the point (4, 5, 1) and its normal is the line joining the points (3, 4, 2) and (1, 1, 1) is

View Answer

Correct choice: B

Explanation:

d.r. of normal to the plane is 3 –1, 4–1, 2–1 = 2, 3, 1
∴ Equation of plane is 2(x –4) + 3(y –5) +1(z –1) = 0 or 2x + 3y + z = 24
