Otherwise its very difficult for me or for Quest to as- sign a grade. JEG 001 10.0 points Which one of the following conic sections has graph 1 2 3 4- 1- 2 1 2- 1- 2- 3- 4 1. 9 x 2- 18 x- 4 y 2- 8 y = 41 2. 4 x 2- 8 x + 9 y 2 + 18 y = 23 correct 3. 4 x 2- 8 x + 9 y 2- 18 y = 23 4. 9 x 2 + 18 x- 4 y 2- 8 y = 41 5. 9 x 2- 18 x- 4 y 2 + 8 y = 41 6. 4 x 2 + 8 x + 9 y 2 + 18 y = 23 Explanation: The graph is a shifted ellipse centered at (1 ,- 1) whose major axis has length 6 and minor axis has length 4. Thus one equation for this ellipse is ( x- 1) 2 9 + ( y + 1) 2 4 = 1 , which after expansion and simplification can be rewritten as 4 x 2- 8 x + 9 y 2 + 18 y = 23 ....
