Yes in that given general equation its, h, k.. so in your equation what is h and k?

No.. check properly.. if it was 1 and 3.. the equation to the ellipse would be (x1)^2 + 4(y3)^2 = 9

You should check your definitions (google works) See http://www.mathwords.com/v/vertices_of_an_ellipse.htm for what the vertex is. You found the center of the ellipse

Your equation is (x+1)^2 + 4(y+3)^2 = 9 in standard form this is \[ \frac{(x+1)^2}{3^2}+\frac{(y+3)^2}{(\frac{3}{2})^2}=1 \] The semimajor axis is the longest axis. Here it is 3 (denominator of x term) the center is (1,3) and when y= 3 you are on the semimajor axis. x= 1+3= 2 or x= 13= 4 and the vertices are (4,3) and (2,3)
