The equation of an ellipse with center at the origin, major axis along the x-axis, and length of major axis 8 and eccentricity 1/2 is: A. x²/16 + y²/12 = 1 B. x²/12 + y²/16 = 1 C. x²/32 + y²/28 = 1 D. x²/28 + y²/32 = 1 ...
1. Find the equation of this ellipse:First, let's mark the center point on the graph to make things more clear.The center point is (1, 2). We can also tell that the ellipse is horizontal. Let's identify a and b. Counting the spaces from the center to the ellipse lengthwise, we ...

In order to derive the equation of an ellipse centered at the origin, consider an ellipse that is elongated horizontally into a rectangular coordinate system and whose center is placed at the origin.The foci are on the x-axis at (-c,0) and (c,0) and the vertices are also on the x-...
Writing an Equation of an Ellipse: SMART Board Resource for Algebra 2 (Grades 6-12) (eLesson Plan)
Can you determine the values of a and b for the equation of the ellipse pictured in the graph below? Problem 2 Can you determine the values of a and b for the equation of the ellipse pictured below? Problem 3 What are values of a and b for the standard form equation of the ellipse...
Yesterday I wrote about theequation of a circle through three points. This post will be similar, looking at the equation of an ellipse or hyperbola through five points. As with the earlier post, we can write down an elegant equation right away. Making the equation practical will take more ...
