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 + (y9)^2 = 9
3) Find the center (h,k) and radius r of the circle with the given equation.
(x7)^2 + (y1)^2 = 81
center = (7,1) radius =9
Are these correct?
