Explanation:
Given :
- Points are A(6 , 5) and B(-4 , 3).
To Find :
- A relation between x and y.
Solution :
Let, P(x, y) be equidistant from the points
A(6 , 5) and B(-4 , 3).
.°. AP = PB
=> √(x - 6)² + (y - 5)² = √(x + 4)² + (y - 3)²
[ Squaring on both sides, we get ]
=> (x - 6)² + (y - 5)² = (x + 4)² + (y - 3)²
=> x² - 12x + 36 + y² - 10y + 25 = x² + 8x + 16 + y² - 6y + 9
=> -12x - 10y + 61 = 8x - 6y + 25
=> -12x - 8x - 10y + 6y = 25 - 61
=> -20x - 4y = -36
=> 20x + 4y = -36
=> 5x + y = -9
Hence :
A relation between x and y is 5x + y = -9.
