engineering mathematics MCQ #1833

  1. Question 1

    Q1. The distance of the point (1, 2) from the line 3x + 4y = 5 is

    • A) |3 + 8 - 5| / √(3² + 4²)
    • B) |3 - 8 + 5| / √(3² + 4²)
    • C) |3 + 8 + 5| / √(3² + 4²)
    • D) |3 - 8 - 5| / √(3² + 4²)

    Answer: |3 + 8 - 5| / √(3² + 4²)

    Explanation: Using distance formula: |Ax1 + By1 - C| / √(A² + B²) = |3*1 + 4*2 - 5| / √(3² + 4²)
