Question

if AB is a diameter of a circle with Centre O, find point B if A and O are (4,-1)and (1,- 3) respectively​

Answer 1

Answer:

(-2,-5)

Step-by-step explanation:

by the the using of mid point formula between of two given

points.

Answer 2

Point B coordinates are (2,-5)

Explanation:

Since AB is diameter of circle with centre O

O is the mid point of AB

OA = OB

(coordinates of A + coordinates of B)/2 = coordinates of O

let the coordinates of B (x,y)

for  x coordinate

$\frac{4+x}{2} = 1$

4+x = 2

x = 2

for y coordinate

$\frac{-1+ y}{2} = -3$

-1 + y = -6

y = -5

coordinates of B(2,-5)
