Equation for the Path of Circle's Center

If a circle of radius 2 is made to roll along the x-axis, what is an equation for the path of the center of the circle?

Looking to get started here. Any hints?

x may be anything but y must always be 2.

If x can be any number and y does not change, then the equation for the path is a line through the point (0, 2).

I say the equation is y = 2.

Yes?

Yes.


Every living thing has no choice but to execute its pre-programmed instructions embedded in it (known as instincts).
But only a human may have the freedom and ability to oppose his natural robotic nature.
But, by opposing it, such a human becomes no more of this world.

Ok. Let's say the question is stated this way:

If a circle of radius 2 is made to roll along the y-axis, what is an equation for the path of the center of the circle?

In this case, the equation is x = 2. Right?

I should pad myself on the back. Not bad someone who didn't major in mathematics.
