Question

find the coordinates of point A where AB is the diameter of a circle whose center is (2,-3) and B is (1,4)

Answer 1

hope it helps you.......

Answer 2

Apply the midpoint formula
Let cordinate of A be x1 and y2
Of B be x2 qnd y2
Of center be x and y
(X1 + x2 )/2. = X
(X1 +2) /2. = 2
X1 + 2 = 2×2
X1 = 4-2
X1 = 2

(Y1 + y2)/2 = y
(Y1 + 4)/2= (-3)
Y1 + 4 = -3× 2
Y1 = -6-4
Y1= -10
