Question

8.Determine the angle θ through which the conic with each equation should be rotated. Then write the

equation in standard form.

18x² + 12xy + 13y² - 198=0

a= 326.3°; (x')²/9 + (y')²/22=1

b= 33.7°; (x')²/9 + (y')²/22=1

c= 33.7°; 9(x')² + 22(y')²=1

d= 33.7°; (x')²/9 - (y')²/22=1


  • For number nine can you just show me how to do the work:

9.Graph (x' + 1)²= -16(y' + 3) if it has been rotated 45° from its position in the xy-plane.
