Solution
Correct Answer:
2x + 3y + 4z = 20
- Identify Normal: A plane perpendicular to a line has the line's direction ratios as its normal vector. Here, n=(2,3,4).
- Point-Normal Form: Use the formula A(x−x1)+B(y−y1)+C(z−z1)=0.
- Substitution: Substitute point (1,2,3) and normal coefficients: 2(x−1)+3(y−2)+4(z−3)=0
- Simplification: 2x−2+3y−6+4z−12=0⟹2x+3y+4z−20=0 ∴2x+3y+4z=20.
