Which equation represents a line which is parallel to y=0 Answer x=1 y=x+3 y=x y=6

The equation that represents a line which is parallel to $y=0$ is $y=6$.<br /><br />Explanation:<br />The equation $y=0$ represents a horizontal line along the x-axis. A line parallel to this line would also be horizontal and have the same slope, which is 0. The equation $y=6$ represents a horizontal line that is parallel to the x-axis, and it has the same slope as $y=0$. Therefore, the correct answer is $y=6$.
