A triangle has vertices at B(-3,0), C(2, -1), D(-1,2). Which transformation would produce an image with vertices B"(1, -2), C"(0, 3), D"(3, 0)? (x, y) - (x + 1, y + 1). (x, y) - (y, x):
(x, y) - (x + 1, y + 1), (x, y) + (-x, y),
O (X, Y) - (x, -y). (x, y) - (x + 2 y + 2)
O(x, y) + (-x, y). (x, y) - (x + 2 y + 2)

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
