Answer:

Length of the diameter of the circle = 10 units long

Explanation:

Given points A (0, -7) and B (8, -1):

We can determine the diameter of the circle by solving for the distance between the two given points.

We'll use the following distance formula:


d = \sqrt{(x_(2) - x_(1))^(2) + (y_(2) - y_(1))^(2) }

Let
(x_(1), y_(1)) = (0, -7)


(x_(2), y_(2)) = (8, -1)

Plug in these values into the distance formula


d = \sqrt{(x_(2) - x_(1))^(2) + (y_(2) - y_(1))^(2) }


d = \sqrt{(8 - 0)^(2) + (-1 - (-7))^(2) }


d = \sqrt{(8)^(2) + (-1 + 7)^(2) }


d = \sqrt{(8)^(2) + (6)^(2) }


d = √(64 + 36)


d = √(100)

d = 10

Therefore, the distance between points A and B is 10 units long.
