Answer 3

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?

Answer 4

I don't know.

Answer 5

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.
