The line y = -2 is parallel to which axis?

Answer and explanation

Correct answer: x-अक्ष

The governing concept is the coordinate form of horizontal and vertical lines. In y = -2, the y-coordinate remains fixed at -2, while x may take every real value. Thus the points on the line are (x, -2), and the line extends horizontally from left to right. Every horizontal line is parallel to the x-axis, so option A is correct. Its slope is 0, which also confirms the conclusion. A line parallel to the y-axis must be vertical and have a constant x-coordinate, such as x = -2. The line y = x is diagonal with slope 1, and x = -2 is itself vertical; neither has the same direction as y = -2.
