Write the standard equation of the circle if the center is (-1,2), and a point on the circle is (2,6).

ladessa [460]

Answer:

(x + 1)² + (y - 2)² = 25

Step-by-step explanation:

The center is given:

(-1, 2)

Find the radius, the distance from the center to a point (2, 6)

r² = (2 - (-1))² + (6 - 2)² = 3² + 4² = 25
r = √25 = 5

Use circle formula:

(x - h)² + (y - k)² = r²
(x - (-1))² + (y - 2)² = 5²
(x + 1)² + (y - 2)² = 25
