Question

Write the equation in standard form for the circle that has a diameter with endpoints (- 1, 12) and (- 1, 8)​

Answer 1

The equation in standard form is
`(x + 1)^(2) + (y - 10)^(2) = 4`

Explanation:

The distance from (-1, 12) to (-1, 8) = 4 = diameter of the circle. So, 2 = radius

The center of the circle is at (-1, 10)

The equation in standard form is
`(x + 1)^(2) + (y - 10)^(2) = 4`
