Question 11

Coordinate Geometry

Find the equation of the line passing through (0, −1) and parallel to the y-axis.

  1. A.y = −1
  2. B.y = 0
  3. C.x = 0
  4. D.x = −1
Show the answer and explanation

Answer: C (x = 0)

Explanation

A line parallel to the y-axis has equation x = constant. It passes through a point with x = 0, so the line is x = 0.
