Question

Write the equation of the circle with center(-3,-2) and (4,5) a point on the circle

Answer 1

Explanation:

(x+2)^2+(y+3)^2=100

Answer 2

(x + 3)^2 + (y + 2)^2 = 98.

Explanation:

(x - h)^2 + (y - k) ^2 = r^2 ( center is (h, k) and r = radius.)

So we have:

(x + 3)^2 + (y + 2)^2 = r^2

When x = 4 y = 5, so

(4 + 3)^2 + (5 + 2)^2 = r^2

r^2 = 7^2 + 7^2 = 98
