Answer:

Step-by-step explanation:
Given Equation:
y=? at x= 1
Putting the given value of 'x' in the equation:

At
, the value of y is 
One leg is horizontal, on the line y=3. Another leg is vertical, on the line x=1. The point where these intersect, D(1, 3) is the vertex of a right angle. Any right triangle inscribed in a circle has its hypotenuse as the diameter of the circle.
Since the triangle is a right triangle, the circumcenter is the midpoint of the hypotenuse: ((8, 3) + (1, -5))/2 = (4.5, -1).
Again, just simple addition and subtraction: $1,034.52
