Identify the graph of 3x² + y2 = 9 for T (-13) and write an equation of the translated or rotated graph in general form.
a. parabola; 3x2 + y2 + 3x – 3y + 3 = 0
c. parabola; 3x2 + y2 + 6x - 6y+ 3 = 0
b. ellipse; 3x2 + y2 + 3x – 3y + 3 = 0
d. ellipse; 3x2 + y2 + 6x - 6y+ 3 - 0
we have the equation
3x² + y^2 = 9
3x^2+y^2=3^2
Divide by 9 both sides
(3/9)x^2+(1/9)y^2=9/9
x^2/3+y^2/9=1
this is the equation of a elipse
