  1. Question 1

    Q1. The equation of the line passing through (1, 2) with slope 3 is

    • A) y - 2 = 3(x - 1)
    • B) y + 2 = 3(x + 1)
    • C) y - 2 = -3(x - 1)
    • D) y + 2 = -3(x + 1)

    Answer: y - 2 = 3(x - 1)

    Explanation: Using point-slope form: y - y1 = m(x - x1), where m = 3, (x1, y1) = (1, 2), so y - 2 = 3(x - 1)
