Question

Identify the graph of the equation. What is the angle of rotation for the equation? 2xy – 9 = 0

a. hyperbola; 90° c. ellipse; 30° b. hyperbola; 45° d. ellipse; 60° Please select the best answer from the choices provided A B C D

Answer 1

there you go ..................

Answer 2

B. Hyperbola; 45 degrees

Explanation:

refer to the image, it is what the equation looks like graphically.

it's a hyperbola with the x- and y-axis as asymptotes.

90 degrees means that it would shift into the II and IV quadrants, so 45 degrees means that it would stay in the I and III quadrants.

also by simplifying the equation you get xy=9/2 which also equals 4.5-
