how do you graph y=2?

Draw a straight horizonal line that passes through y = 2 on the (vertical) y axis. It should extend over the full width of the graph.

Yes, y=2 is the equation of the line that contains all the points which have their ycoordinates as 2, such as (3,2), (5,2), (4,2), etc. Plot those. You'll see that they all lie on a horizontal line which is 2 units below the xaxis. That line is the graph.

Because it not greater or lesser than so the line will only be drawn on figure 2, on yaxis

Because it not greater or lesser than so the line will only be drawn on figure 2, on yaxis on the left side where we have the nagative numbers.
