Question

How do I graph the equation `(x+2)^2/9+(y-3)^2/25=1` on an Nspire?

Answer 1

`((x+2)^2)/9+((y−3)^2)/25=1` is an equation for an ellipse, which can easily be graphed on the TI-nspire!

Step 1: Open a new Document, with the Graphing application.
Step 2: Press Menu, Graph Entry, Equation, Ellipse (there is only one form).

Step 3: Enter in the correct information from your equation: the center is (-2,3), and the denominator for the x-term is `3^2`, so enter 3, and the denominator for the y-term is `5^2` so enter 5.

Step 4: Press Enter.

Step 5: If you don't like the positioning of the graph, I chose to grab the paper with the "hand" and drag the paper a little bit so I could see all of the ellipse.
