Question 687025
25(x-1)^2 + 9(y+3)^2=225 identify the curve?
put in standard form then identify the curve.
**
standard form for an ellipse with vertical major axis:
{{{(x-h)^2/b^2+(y-k)^2/a^2=1}}}, a>b, (h,k)=(x,y) coordinates of center
{{{25(x-1)^2+9(y+3)^2=225}}}
divide both sides by 225
{{{(x-1)^2/9 + (y+3)^2/25=1}}}
Given equation is that an ellipse with vertical major axis and center at (1,-3)
