These questions that I have completed are on a test review for my exam and I would just like to know if they are correct. These are only a few of the questions, I have more that are just not complete yet. Thank You!

1) List the intercepts for the graph of the following equation.

y^2 = x + 49

I plugged in 0 for x and then y and I got (-49,0) and (0,7).

2) Write the standard form of the equation of the circle with radius and center (h,k)

r=3 (h,k)=(-6,9)

(x+6)^2 + (y-9)^2 = 9

3) Find the center (h,k) and radius r of the circle with the given equation.

(x-7)^2 + (y-1)^2 = 81

center = (7,1) radius =9

Are these correct?
