Question

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

• A. 3x + 2 = 0
• B. 3y + 2 = 0
• C. 3x + 2y = 0
• D. 3x - 2y = 0

Answer 1

The correct option is B

3y + 2 = 0

A line parallel to the x-axis is of the form y = k
$3y+2=0,\text{can be written as},y=-\frac{2}{3}$
Thus, 3y + 2 = 0 is parallel to x axis.
