What is the equation of the circle with center (-1,-2) and passes through the point (6,4)?

which of the following points is also located on the circle?
a. (6,-6)
b. (-10,0)
c. (-6,4)

and B

Step-by-step explanation:

To write the equation of a circle, use the formula where the center of the circle is (h, k).

This means the equation is .

Find the radius r by finding the distance between (-1,-2) and (6,4) using the distance formula.

Since the radius is √85 and therefore .

The equation is .

To see what other point is on the circle, substitute the (x,y) in the equation.

(-10+1)^2 + (0+2)^2 = 85

81 + 4 = 85

85 = 85

The point (-10,0) is on the circle.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

good luck on your studies! : )
