Homework Assignment 3

Put the following equations in standard form (you will need to use completing the square), find the coordinates of the vertices of the major and minor axes and foci for each ellipse, and graph each ellipse.

1. x² + y² + 16x - 2y = -10
2. 4x² + 9y² - 16x + 18y = 11
3. 7x² + 2y² + 6x - 2y = 0
4. 3x² + y² + 78x = 2
5. -9x² + 7y² - 126x - 8y = -7
