Y-5=0 graph linear equation

Well, with the equation in that form, it may not be obvious how to graph it.
So let's change just the form a little bit... without changing the equation:

                                y - 5 = 0

Add  5  to each side:    y = 5   

Look at that for awhile, and think about what it tells us.

It says that 'y' doesn't depend on 'x' at all.  No matter how far left or right
you go on the graph, the y-value of every point is 5 .

The graph is a horizontal line across the graph.  It cuts across the y-axis at
the point where  y=5 , and it stays exactly at that same height everywhere.
