What would the #(x,y)# table look like for a horizontal and a vertical line graph?

A horizontal line would have the equation #y="number"#, so the table would have the same number for #y# whatever the value of #x#
In this case #"number"# stands for the distance of the horizontal line from the #x# axis (positive or negative = above or below).

With a vertical line it's the other way around. The equation is #x="number"#, so whatever the #y# value the #x# value stays constant.
In this case #"number"# stands for the distance of the vertical line from the #y# axis (positive or negative = right or left).
