Answer:
B. (-7,-3)
Step-by-step explanation:
Given the circle:
The point (x,y) which lie on the circle are the coordinate which satisfies the given equation of the circle.
We now consider the given options.
<u>Option A (5,12)</u>
When x=5, y=12
<u>Option B (-7,-3)</u>
When x=-7, y=-3
<u>Option C (-6,-10)</u>
When x=-6, y=-10
<u>Option D (6,23)</u>
When x=6, y=23
We can see that only (-7,-3) satisfies the equation of the circle. Thus it is the point which lies on the circle.
The correct option is B.
Exact form : r=2squareroot2, -2squareroot2
Decimal form : r=2.8284212...,-2.82842712....
Step-by-step explanation: Take the root of both sides and then solve.
Hope this helps you out.
