What is the distance of the point from the line ?

Answer and explanation

Correct answer: A. 0

  1. Step 1: The perpendicular distance from a point to a straight line is given by .
  2. Step 2: Substitute point and line coefficients , , : numerator , and denominator .
  3. Step 3: Divide numerator by denominator: .
Answer
0.
Why not the others: 1 adds rather than subtracts the constant term in the final step; 1/5 uses an incorrect distance denominator or incorrect numerator coefficient or dropped term; -1 omits the factor of 2 in the denominator during simplification.
