Find the equation of a straight line which is parallel to y-axis, and is at a distance of b from y-axis.


Answer:

x = b

Step by Step Explanation:
  1. If a line is parallel to the y-axis and is at a distance of b from the x-axis as shown in the figure below, we observe that the abscissa of all the points on the line is constant and equal to b.
  2. This means that the equation of this line should be x = b.
