Question

When the Y-coordinates of two points lying on a line are non-zero and equal, and the X-coordinates are unequal, then :

• A. The line is Parallel to the X-axis.
• B. The line is Parallel to the Y-axis.
• C. The line is inclined at an angle of ${45}^{\circ }$ with the positive direction of the X-axis.
• D. None of the above.

Answer 1

Answer: (A)

The line is Parallel to the X-axis.

Equal y coordinates and unequal x coordinates means that the two points are equidistant from X axis and hence line containing them is parallel to x axis.
