Question

The center of a circle is (4, 6), and an endpoint of a diameter is (2, 5). What is the other endpoint of the diameter?

Answer 1

Consider this option:
1. if the point (4;6) is the centre of the circle and the point (2;5) is the first endpoint of its diameter, then point (4;6) is the middle point of the diameter (it means that is the middle between the 1st and the 2d endpoints of diameter).
2. using the property described above:
for x of the 2d endpoint of the diameter: x=4*2-2=6;
for y of the 2d endpoint of the diameter: y=6*2-5=7.

answer: (6;7)

Answer 2

(6,7)

Explanation:

The center of a circle is (4, 6), and an endpoint of a diameter is (2, 5)

Since center is the mid point of two end points of diameter .

So, we will use mid point formula

`(x,y)=(4,6)`

`(x_1,y_1)=(2,5)`

Mid point formula :
`x =(x_1+x_2)/(2)` and
`y =(y_1+y_2)/(2)`

Substitute the values

`4 =(2+x_2)/(2)` and
`6 =(5+y_2)/(2)`

`8 =2+x_2` and
`12 =5+y_2`

`6=x_2` and
`7=y_2`

Thus [tex](x_2,y_2)=(6,7)/tex]

Thus the other endpoint of the diameter is (6,7)
