Question

find the coordinate of a point A where AB is the diameter of a circle whose center is C(1 , -3 ) and B is (-2 , -5 )​

Answer 1

Answer:

x=4 and y= -1

Step-by-step explanation:

let coordinate of A be (x,y)

AB is a straight line whose centre is C

so we know

C(1,-3) =( coordinate of A+ coordinate of B)/2

C( 1,-3) =[ {x+(-2)}/2 {y+(-5)}/2]

C( 1,-3) =[ (x-2)/2 (y-5)/2]

so

( x-2)/2=1 (y-5)/2= -3

x-2=2 y-5= -6

x=2+2 y= -6 +5
