 Question 254907: i do not understand how to put an equation into a graphing calculator. The problem i am working on asks how you would put this in to graph an ellipse 9x^2+25y^2=225 but i dont know what how to do it on a calculatorAnswer by jim_thompson5910(28598)   (Show Source): You can put this solution on YOUR website!In order to graph, you need to solve for y Start with the given equation. Subtract from both sides. Divide both sides by 25. Take the square root of both sides (don't forget about the plus/minus) or Break up the plus/minus to form two separate equations. So the two equations that you would enter into your calculator would be and If you enter them in, you should get the graph: Take note that the red graph is and the green graph is which both form the graph of
