Since it is not a function, you need to solve of y and you will have TWO equations. A plus and a minus one. FOR EXAMPLE the ellipse x^2/4+y+2/16=1 you could solve it as y^2/16=1-x^2/4 then multiply by 16 y^2=16(1-x^2/4) Now you have y=+ Square root of (16(1-x^2/4)) AND y=-Square root( 16(1-x^2/4)) IF you enter both of those and graph them on the same graph you will have an ellipse.

Can you use a graphing calculator on a NY Regents Exam?
Graphing calculators are *required* for students taking the Algebra, Geometry, and Algebra II/Trig Regents exams. Schools may not require students to purchase their own graphing calculators for these courses: "Under no circumstances should students be charged for a calculator or otherwise required to purchase one in order to participate in an educational program." http://www.emsc.nysed.gov/mgtserv/charging_for_calculators.shtml Graphing calculators are specifically forbidden on the Earth Science, Living Environment, and Chemistry Regents exams. They are permitted on the Physics exam. http://www.emsc.nysed.gov/osa/08-09memo/jun-aug-09/730/541-809.pdf As required by the state, your graphing calculator has to have its memory cleared before you take the exam. Many schools have a program that will do this automatically, and will clear your calculator before you enter the exam room. Be sure to back up any data onto your computer before the exam.
How do you solve quadratic equations on a graphing calculator?
If you have a TI-89: Hit "F2", select "solve." Enter your equation, which may or may not be in the following form: Then fill in values for your variables (a, b, and c) and solve for x. Your syntax will be: solve(ax^2+bx+c=0,x) * Also, if you are interested, you can download a software package for your TI graphing calculator to help you improve your score on the SAT test at www.calc-tech.com . It's called the SAT Operating System (SAT_OS) and can be used during the actual test to reduce time on math problems and improve the accuracy of your calculations.
How do you determine the solutions on a graph for a quadratic equation?
The X-Intercepts are the solutions. If you have an algebra calculator, you can usually find them by going to CALC>Zero>enter the left and right boundaries for each side.

How can you enter 3.75 million in a calculator?
That depends on what kind of calculator you have. 3.75 million would be 3750000. But on a scientific calculator you could also enter it as 3.75[EE]06 which is the same as 3.75*10^6.

How do you solve equations on a TI-83 graphing calculator?
2nd [CATALOG], solve( , enter equation, variable and guess after the bracket, close brackets with " ) ". You can also put lower and upper bounds after the guess.
How you can solve equations with graphing?
An equation to be graphed must be written (or must be entered in a graphing calculator) in the form y = ..., that is, y must be expressed as a function of x. After a graph is displayed in your graphing calculator, you can use the calculator's TRACE feature to find the x-intercept(s) (a point that the graph intersects the x-axis where y = 0). Move the TRACE cursor to a point just below the x-axis and press ENTER, MOVE the TRACE cursor to a point just above the x-axis and press ENTER, press ENTER again. In this way you can find the x-intercept(s). Thus, each x-intercept of the function is a real solution of the equation to any desired degree of accuracy.
