Answer 2

I just answered this question....

Answer 3

the equation of a circle is (x-a)^2+(y-b)^2=r^2
r is the radius and (a,b) the center of the circle

Answer 4

the equation is (x-4)^2+(y-0)^2=3^2
or x^2+y^2-8x=-7

Answer 5

the graph is easy, you know the center and the radius, to find the four points you just pick a value of x and solve for y
