Question 33

Coordinate Geometry

The midpoint of the segment of the line y = 4x + 3 which lies between the x-axis and the y-axis is

  1. A.(−3/2, 3/2)
  2. B.(−2/3, 3/2)
  3. C.(3/8, 3/2)
  4. D.(−3/8, 3/2)
Show the answer and explanation

Answer: D ((−3/8, 3/2))

Explanation

The line meets the x-axis at (−3/4, 0) and the y-axis at (0, 3). The midpoint is (−3/8, 3/2).
