Given : point (x,y) is equidistant from (6,5) and (-4,3).
To find : relation between x and y
Solution:
point (x,y) is equidistant from (6,5) and (-4,3).
=> √(x - 6)² + (y - 5)² = √(x -(-4))² + (y - 3)²
=> (x - 6)² + (y - 5)² = (x + 4)² + (y - 3)²
=> x² - 12x + 36+ y² -10y + 25 = x² + 8x + 16 + y² - 6y + 9
=> -20x - 4y + 36 = 0
=> -5x - y + 9 = 0
=> 5x + y = 9
Another way :
Slope of (6,5 ) and (-4 , 3)
= 1/5
sloe of perpendicular line = - 5
Mid point of (6,5 ) and (-4 , 3) = (1 , 4)
Equation of line = y - 4 = (-5)(x -1)
=> y - 4 = -5x + 5
=> 5x + y = 9
