The circle graphed with the equation x² + y² = 2.25 is the circle C

The solutions are (0.44, 1.44) and (-1.44, -0.44)

Determining the circle graphed with the equation

From the question, we have the following parameters that can be used in our computation:

The circles

Where, we have the following properties about the circle C

Center = (a, b) = (0, 0)

Radius, r = 1.5 units

The equation of the circle C is represented as

(x - a)² + (y - b)² = r²

Substitute the known values into the equation

(x - 0)² + (y - 0)² = 1.5²

Evaluate

x² + y² = 2.25

Hence, the equation of the circle C is x² + y² = 2.25

Next, we plot the two equations

x² + y² = 2.25 and y - x = 1

The solution is the point of intersection

In ths case, the points are (0.44, 1.44) and (-1.44, -0.44)
