PLEASE HELP!!! Which of the following is the equation of a line that passes through the point (1,4) and is parallel to the x-axis? A. x=4B. x=1C. y=1D. y=4

The answer is D. y=4. I've attached an image of what the graph looks like.
A you can see, all the values of y are 4 so the graph goes through (1,4) and is also parallel to the x axis, which has the equation y=0
