Question

Which of the following equations represents a line parallel to the x-axis?

• A. x = 2
• B. x = -12
• C. y = 10
• D. y = -8

Answer 1

Answer: (C), (D)

The correct options are
C y = 10
D y = -8

If a line is parallel to the x-axis, its distance from the x-axis is the same and it is represented by y = c (c is a constant value).

Hence,
y = 10 and y = -8 are equation of lines parallel to the x-axis.
