# Equation of Lines Parallel to Axes

**(i) Equation of a Line Parallel to the X-Axis:**

Consider that is the straight line which is passing through the point and is parallel tothe -axis because this point lies on the -axis and any point on the Y-axis whose values of are zero.

Then the equation of a line parallel to the **X**-axis is given by

**(ii) Equation of a Line Parallel to the Y-Axis:**

Consider that is the straight line which is passing through the point and is parallel to the -axis, because this point lies on the -axis and any point on the X-axis whose values of are zero.

Then the equation of a line parallel to the Y-axis is given by
