You have a horizontal line. There is an infinite number of points on the line. Every point has the same y-coordinate. What is the y-coordinate of every point on the line?

Look at point A which is on the line. To get to point A from the origin (the point where the x- and y-axes cross), you go 3 units to the right and 3 units up. 3 units to the right means the x-coordinate is 3. 3 units up means the y-coordinate is also 3.
