I tried this:

Explanation:

In this case you can say that regardless of the #x# value you choose the corresponding #y# value will always be equal to #3#, so that you will get points with coordinates:

#("any value",3)#

so when you plot these points you get a straight horizontal line that passes through #y=3# and is parallel to the #x# axis:
graphically:

graph{0*x+3 [-10, 10, -5, 5]}
