Practicing Success
A point on the y-axis which is equidistant from the points A(6, 5) and B(-4, 3) is: |
(0, 9) (0, -9) (9, 0) (0, 6) |
(0, 9) |
Let point on y-axis is C( 0 , y ) From point to A(6 , 5) to (0 , y) , Distance from A = \(\sqrt { ( 0-6)² + ( y - 5 ) ² }\) Distance from B = \(\sqrt { ( 0-4)² + ( y - 3 ) ² }\) As, Point C is equidistance from Point A and B \(\sqrt { ( 0-6)² + ( y - 5 )² }\) = \(\sqrt { ( 0-4)² + ( y - 3 ) ² }\) 36 + y² + 25 -10y = 16 + y² + 9 - 6y y = 9 So, Point C ( 0 , 9 ) The correct answer is Option (1) → (0, 9) |
