It is (x + 2)^2 + (y + 3)^2 = 9
Points: (2, -3) and (-2, 0) Slope: -3/4 Equation: y = -0.75x-1.5
Equation of any circle, with any radius, and its center at any point: [ x - (x-coordinate of the center) ]2 + [ y - (y-coordinate of the center) ]2 = (radius of the circle)2
The secant of a circle passes through the center of a circle sometimes
The general equation of a circle is given by the formula(x - h)2 + (x - k)2 = r2, where (h, k) is the center of the circle, and r its radius.Since the center of the circle is (0, 0), the equation reduces tox2 + y2 = r2So that the equation of our circle is x2 + y2 = 36.
No, the cord of a circle does not have to go through the center of that circle. A chord that does go through the center of a circle is a special case and is called the diameter. A chord can connect any two points on a circle.
The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2

a diameter
(x - A)2 + (y - B)2 = R2 The center of the circle is the point (A, B) . The circle's radius is ' R '.
Points: (2, -3) and (-2, 0) Slope: -3/4 Equation: y = -0.75x-1.5
Equation of circle: (x-3)^2 +(y-2)^2 = 8

Well, honey, the center of that circle is simply the point (3, 9). You see, the equation you provided is in the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle. So, in this case, the center is at (3, 9). That's all there is to it, sugar.
Equation of any circle, with any radius, and its center at any point: [ x - (x-coordinate of the center) ]2 + [ y - (y-coordinate of the center) ]2 = (radius of the circle)2
32+62=45 so the standard form is x2+y2=45
The secant of a circle passes through the center of a circle sometimes
The equation of a circle with center (0,2) and radius r is x^2+(y-2)^2=r^2 Since it passes through (0,0) (the origin) 0^2+(0-2)^2=r^2 r^2=4 The equation of the circle is x^2+(y-2)^2=4
