Question

Which of the following options is the equation of a line parallel to the x-axis?

Option #1: y=3x


Option #2: y=3


Option #3: x=3y


Option #4: x=3


(1 point)
The equation of a line parallel to the x-axis is Option #
.

Answer 1

The equation of a line parallel to the x-axis is one that has a constant value for \( y \) and does not change regardless of \( x \). This is represented by the equation \( y = c \) where \( c \) is a constant.

Among the options, Option #2: \( y = 3 \) is the correct answer, as this represents a horizontal line where \( y \) is always 3, and it is parallel to the x-axis.

So, the equation of a line parallel to the x-axis is Option #2.
