Answer 2

(d) x=a is the equation of the line parallel to y-axis.

Explanation:

• An algebraic form of representing the set of points is the equation of a line.
• In the coordinate axis, the points that form a line are represented as x, y and it forms a equation called equation of a line.
• The equation of a line parallel to y-axis is x=a, where a is x-coordinate.
• For example, the equation of a line parallel to y-axis has (2,3) is x=2.
• The equation of a line that is parallel to x-axis is y=a, here a is the y-coordinate.
• Therefore, option d is correct.
