You can  put this solution on YOUR website! Pick any value for x. Say x=1. The equation tells you the y coordinate =4 
(1,4) 
Now pick another value for x. Say x= 3.The equation tells you the y coordinate =4 
(3,4)
 
Plot them both and draw the line. What did you get?
 
A horizontal line through (0,4)
