You can put this solution on YOUR website! Is the following a horizontal line, vertical line, or neither? x=18 is vertical. For any y, it's 18 units to the right of the y-axis.
 ----------------
 y=29x is a steep straight line, neither vertical nor horizontal.
 -------------
 y=45 is horizontal.  For any x, it's 45 units above the x-axis.
