Question 66711
We can tell that the center is at (1,2) in (h,k) form.
The distance from the center to the farthest verticies is {{{a}}}.
The distance from the center to the closest certicies is {{{b}}}.
{{{a = 3}}}
{{{b = 1}}}
Equation for horizontal Ellipse:
{{{(x - h)^2/a^2 + (y - k)^2/b^2 = 1}}}
{{{(x - 1)^2/9 + (y - 2)^2/1 = 1}}}
{{{graph(300,300,-5,5,-5,5,sqrt(1 - (x - 1)^2/9) + 2,-sqrt(1 - (x - 1)^2/9) + 2,2)}}}
