Let A = (1, 5) and B = (3, −1). Verify that P = (8, 4) is equidistant from A and B. Find at least two more points that are equidistant from A and B. Describe all such points.

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books
