What is the distance of the point from the line ?
Answer and explanation
Correct answer: D. 3/5
- Step 1: By the point-to-line distance theorem, .
- Step 2: Insert the line coefficients and point coordinates: .
- Step 3: The resulting perpendicular distance is .
Answer
3/5.
Why not the others: 7/10 uses an incorrect distance denominator or incorrect numerator coefficient or dropped term; 6/11 uses an incorrect distance denominator or incorrect numerator coefficient or dropped term; 6 computes the numerator without dividing by .
