Step-by-step explanation:
A locus can be defined as a curve or figure formed by all the points satisfying a particular equation of the relation between coordinates.
The condition stated in the question is such that a generic (x,y) point of the curve is equidistant from the points A(2,3) and B(6,1).
The distance d1 from (x,y) to (2,3) is:
The distance d2 from (x,y) to (6,1) is:
Since d1=d2:
Squaring both sides:
Operating:
Simplifying all the squares:
Moving the variables to the left side and the numbers to the right side:
Simplifying:
Dividing by 4:
Or, equivalently:
