Math Problem Statement

Two points on a circle are given: A(-1, 8) and B(5, -2). Several questions follow regarding the circle, such as finding the center, radius, and determining if certain points lie on the circle.

Solution

The image contains a geometric problem related to a circle and its properties. Let's break down the text and analyze the questions:

Translation of the questions:

  1. Part a: Where is the center of the circle?

  2. Part b: What is the radius of the circle?

  3. Part c: Does the point (6,−4)(6, -4) lie on this circle?

  4. Part d: If the point (1,k)(1, k) lies on this circle, what is the value of kk? Define the equation of the circle.

  5. Part e: This circle intersects the x-axis. At which points does the circle intersect the x-axis? Find the points of intersection with the help of the circle's equation.
