Question

The end point of a diameter of a circle are A(0, 0) and B(6, 8). The center of the circle is at the point * 1 point

Answer 1

Answer:

Let AB be a diameter of the circle having its centre at C(1, -3) such that the coordinates of one end A are (4, -1).

Let the coordinates of B be (x,y).

Since C is the mid-point of AB. Therefore,the coordinates of C are(

x+4

,

2

y−1

).

But, the coordinates of C are given to be (1,-3).

∴

x+4

=1and

2

y−1

=−3

⇒x+4=2andy−1=−6

⇒x=−2andy=−5

Hence,the coordinates of B are (-2, -5).
