So we have an ellipse, and here's the equation of our ellipse that we're given to begin with.
00:09
Let's look at a little analysis of this first, and then we'll answer the question that we have.
00:14
So we know that this equation, in the form that we want it to be for graphing, looks like this.
00:24
And so if i do it all just a quick little sketch down here of my ellipse.
00:30
We know that this is acting as little a squared, and that this is acting as little b squared.
00:38
And we see that the graph is elongated in the x direction.
00:41
So a squared is 16, so a is four.
00:44
So we would go out here, four units, and there would be a point at four zero.
00:50
And likewise, one centered over here, because we're centered at zero zero.
00:55
And then our little b squared is four, so b is two, so we would go up two, and we would go down two...
