Find a relation between x and y such that the point (x, y) is equidistant from the point (3, 6) and (- 3, 4)

Solution:

The distance between any two points can be measured using the distance formula which is given by √ [(x₂ ^_-  x₁)² + (y₂ - y₁)²]

Let point P (x, y) be equidistant from points A (3, 6) and B (- 3, 4).

Since they are equidistant, PA = PB

Hence by applying the distance formula for PA = PB, we get

√(x - 3)² + (y - 6)² = √(x - (- 3))² + (y - 4)²

√(x - 3)² + (y - 6)² = √(x + 3)² + (y - 4)²

By squaring, we get

PA² = PB²

(x - 3)² + (y - 6)² = (x + 3)² + (y - 4)²

x² + 9 - 6x + y² + 36 - 12y = x² + 9 + 6x + y² + 16 - 8y

6x + 6x + 12y - 8y = 36 - 16  [On further simplifying] 

12x + 4y = 20

3x + y = 5

3x + y - 5 = 0

Thus, the relation between x and y is given by 3x + y - 5 = 0
