Answer:
Step-by-step explanation:
We want to find the equation of a circle P, and we know that the square RSTU is inscribed in the circle, this means that if we replace the points:
R(0,4) S(6,2) T(4,-4) and U(-2,-2) the equation must be verified.
Then, we have to replace the points in each option to see which one is the correct answer.
Option A:
- R(0,4):
We can see that R doesn't belong to the equation of the circle.
We could replace the rest of the points in the equation, but since we already know that R does not belong to the circle, we already know that it is not the right option.
Option B:
- R(0,4):
The point R(0,4) verifies the equation.
- S(6,2):
The point S doesn't belong to the equation of the circle, then we already know that this isn't the correct option.
Option C:
- R(0,4):
The point R verifies the equation.
- S(6,2):
The point S verifies the equation.
- T(4,-4):
The point T verifies the equation.
- U(-2,-2):
The point U verifies the equation.
<em>We can see that the four points RSTU verifies the equation. This means that the square RSTU is inscribed in circle P whose equation is: </em>
<em>We can see that the graph of the equation verifies the answer.</em>
