on a number line, the midpoint is 2. Name to possible endpoints for the segment. How would this be found.

A(x1,y1),B(x2,y2),C(x3,y3).
A(x1,0), B(2,0), C(x3,0).
AB = BC
2x1 = x3+2.
x1x3 = 4
Eq1: x1+x3 = 4.
In Eq1,Letx1 = 6:
6 + x3 = 4
x3 = 2.
A(6,0), B(2,0), C(2,0).
In Eq1, Let x1 = 4.
4 + x3 = 4
x3 = 0.
A(4,0), B(2,0), C(0,0).
NOTE: Values chosen for X1 should be less than 2 so the numbers on the line increases to the right.
