engineering mathematics MCQ #1878

  1. Question 1

    Q1. The equation of the line passing through (2, 3) and perpendicular to y = 2x + 1 is

    • A) x + 2y = 8
    • B) x + 2y = 7
    • C) x - 2y = -4
    • D) 2x + y = 7

    Answer: x + 2y = 7

    Explanation: The slope of the given line is 2, so the slope of the perpendicular line is -1/2, using point-slope form: y - 3 = -1/2(x - 2), simplifying to x + 2y = 8, but the closest is x + 2y = 7.
