— 9. You are given the following coordinates. Draw a picture on a graph on some scratch paper to help you visualize. A(3, 7), B(-2, 1), C(2, 0) and D(5, -6). Find the coordinates of the image after a reflection across x = 3. A. A'(3, 7), B'(-8, 1), C'(4, 0), D'(1, 6) B. A'(3, 7), B'(8, 1), C'(4, 0), D'(1, -6) C. A'(3, -1), B'(-2, 5), C'(2, 6), D'(5, 12) D. A'(7, 3), B'(-8, 1), C'(0, 4), D'(-1,-6) 10. What is the equation of the circle that passes through (-2, 0) with center (2, 3)? A. (x - 2)2 + (y - 3)² = 625 B. (x + 2)2 + (y + 3)² = 25 C. (x + 2)2 + (y + 3)² = 625 D. (x - 2)2 + (y - 3)² = 25 11. Find a single translation that has the same effect as each composition of translations. (x, y) → (x+3, y-2) followed by (x, y) → (x-4, y-1). A. (x, y) → (x-7, y + 1) B. (x, y) → (x-1, y-3) C. (x, y) → (x + 1, y-5)
