The unsimplified answer to the smart person above (the answer to the test) is
(x-1)^2+(y-4)^2=4
Answer: x² + y² - 2x - 8y + 13 = 0
Step-by-step explanation:
the equation of the circle is in the form (x - a)² + (y - b)² = r²
where (a,b) is the center of the circle and r is the radius
hence the equation is
(x - 1)² + (y - 4)² = 2²
x²-2x+1+y²-8y+16= 4
x²+ y² -2x- 8y + 17 =4
x² + y² - 2x - 8y = -13
x² + y² - 2x - 8y + 13 = 0

There is only one solution on the first one since you can't get 5 any other time then it being 7.
on the other one all real numbers above 7 are answers since after x is 7 it will be greater the. 5 always.
