      Question

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

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

      Solution

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