Is x equals 3 a linear equation?

Yes it is the equation for a vertical line (parallel to the y-axis), intersecting the x-axis at the point (3,0). There is not a y component in this equation, because at any value of y, x will always equal 3.

If the equation is x equals 2 what is y?

That makes no sense, there is no y in the equation so y cannot equal anything.
