[Python] Python Plotting Using Class

I have to define a class point(x,y) that represents a point in a Euclidean plane, which I completed with:

class point():
def __init__(P,x,y):
P.x=x
P.y=y


Now I must extend this class by creating methods that will:

1. Return a point A that is a vertical reflection of P across the horizontal line at y using A=P.verticalReflect(y).
2. Return a point B that translates the point P a distance of x in the x-direction and a distance of y in the y-direction using B=P.translate(x,y).
3. Display a point using pyplot using P.display(options). I should be able to let the user print a label, set the font size and offset from the point.

An example of code that will initiate the class created would be:

P=point(2,3)
P.display(label="P",labeloffset=0.2)

A=P.verticalReflect(y=3.5)
A.display(c="green",label="A",labeloffset=0.1)
plt.axhline(y=3.5,c="k",ls="--")


I'm having trouble figuring out where to start to define these new methods in the class.
