For this case we have the following system of equations:

$y = x\\y = -x + 4$

We want to find the graphical solution of the system of equations. To do this, we graph both lines (See attached image).

The solution of the system is the point of interception of both functions. In this case, the solution is given by:

$(x, y) = (2,2)$

Answer:

$(x, y) = (2,2)$

Answer:

The side of the square is 5.971 cm

Step-by-step explanation:

If the square fits the circle exactly, then its diagonal is equal to the diameter of the circle. Since the side of the square has a length of $x$ cm, then it's diagonal have the length of $x\sqrt2$ cm. Using the circle's area we can find the diagonal of the square, as shown below:
