Question

The coordinates of one end of point of a diameter a b of a circle at 3, 4 in the coordinates of centre at - 1, 0 find the coordinates of the other end of the diameter

Answer 1

.___1__.____1_.

A. B. C

(x,y). (-1,0). (3,4)

Coordinates of B =(x1+x2)/2. ,. (Y1+y2)/2

-1=x+3/2

x=-5

0=y+4/2

y=-2

So A (other end of diameter) is (-5,-2)
