Best ResponseYou've already chosen the best response.0The question say to identify the type of conic section whose equation is given and find the vertices and foci, i am unsure wheter i should mention that its seems to on an angle or do i just go ahead and write down the equation for this ellipse

Best ResponseYou've already chosen the best response.0i have no problem finiding the equation, but its just that it looks tilted on the xy coordinate system, and i am wondering if i should find the angle its tilted on and how would i do so

Best ResponseYou've already chosen the best response.0i see its shifted at what looks like a 45 degree angle, but i am still unclear how to determine its a 45 degree angle
