    Question

    A line passes through the points (2, 3) and (5, βˆ’3).

    Find its equation.
    A 5x + 3y βˆ’ 7 = 0 Correct Answer Incorrect Answer
    B 2x + y βˆ’ 7 = 0 Correct Answer Incorrect Answer
    C 2x + 2y βˆ’ 7 = 0 Correct Answer Incorrect Answer
    D 2x + y βˆ’ 5 = 0 Correct Answer Incorrect Answer

    Solution

    Slope m = (βˆ’3 βˆ’ 3)/(5 βˆ’ 2) = βˆ’6/3 = βˆ’2 Equation in point-slope form: y βˆ’ 3 = βˆ’2(x βˆ’ 2) y βˆ’ 3 = βˆ’2x + 4 2x + y βˆ’ 7 = 0
