Question

6) Find the co-ordinates of the point A, where AB is a diameter of a circle whose
centre is (2.-1) and B is (1.4).​

Answer 1

Answer:

kindly see the answer below...

Step-by-step explanation:

Here, given that

AB is a diameter of a circle whosecentre is (2,-1) and B is (1,4).

so, let assume that the point A be (x, y)

now, by the 1:1 ratio, we get for X-axis......

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

$x = 3$

and, for the Y-axis....

$\frac{y + 4}{2} = - 1$

$y = - 6$

therefore, the co-ordinates of A is (3,-6).
