How do I sketch the graph for this equation?
{x^2+y^2=9
{16x^2+9y^2=144
----------------
I see 2 equations.
------------------
For these 2, solve for x or y, most solve for y.
Then, plug in values for x, and get a value for y to find points on the graph. When you have enough points, connect them with a smooth curved line.
---------------------------
Another way is to dl the (free) software at

and have it done for you.
--------------------------
If you solve for y, then click Function, then Insert Function.
You can also click on Function, then Insert Relationship, and enter the equations as the are above,.
