Where is the variable of x and y?!

Question

What is the output of this code?
class Point {
constructor(x,y) {
this.x = X;
this.y = y;
}
static slopeAB (A, B) {
const dx = A.x-B.x;
const dy = A.y-B.y;
return dy/dx;
}
}
const P1 = new Point(1,2);
const P2 = new Point(3,4); console.log(Point.slopeAB(P1, P2));

Variable of x and y? x and y are already a variable of constructor of class Point.

Here slopeAB is a static method which has two objects A and B which are P1 and P2.
