The distance of the point from the plane is:
Answer and explanation
Correct answer: D.
- Step 1: Apply the distance formula: .
- Step 2: Compute numerator: .
- Step 3: Compute denominator: . Thus .
Answer
.
Why not the others: is the unnormalized numerator; uses denominator ; adds rather than subtracts the constant term in the final step.
