Answer 1

a. The center of the circle will be the coordinate point of the marked point inside the circle.

center: (3,-5)

The radius is the distance between the center and any point on the circle.

radius: 4 units

b. standard form for circles: (x-h)²+(y-k)²=r² where (h,k) is the center

standard form: (x-3)²+(y+5)²=16

c. Simplify equation in standard form to get general form.

(x-3)²+(y+5)²=16

x²-6x+9+y²+10y+25=16

general form: x²+y²-6x+10y+18=0
