Question

The coordinates of the center of a circle are (– 6, 1.5). If the ends of a diameter are (– 3, y) and (x, – 2) then………. A) x = – 9, y = 5 B) x = 5, y = – 9 C) x = 9, y = 5 D) x = –9, y = –5​

Answer 1

Answer:

coordinates of centre = (-6,1.5)

ends of diameter = (-3,y) ; (x,-2)

by section formula,

(-3 + x)/2 = -6

=> -3 + x= -12

=> x = -9

(y - 2)/2 = 1.5

=> y - 2 = 3

=> y = 5

so that,

answer is opt (a) x= -9 , y= 5
