Answer and explanation
Correct answer: C. 2
- Step 1: The perpendicular distance from a point to a straight line is given by .
- Step 2: Substitute point and line coefficients , , : numerator , and denominator .
- Step 3: Divide numerator by denominator: .
Answer
2.
Why not the others: 35/17 uses an incorrect distance denominator or incorrect numerator coefficient or dropped term; 17/9 uses an incorrect distance denominator or incorrect numerator coefficient or dropped term; 34 adds rather than subtracts the constant term in the final step.
