In the following exercises, graph each ellipse.
$16 x^{2} + 9 y^{2} = 144$

Short Answer

Expert verified

The Graph of the given ellipse is given by

Step by step solution

Step 1.Given information

The equation of the ellipse is $16 x^{2} + 9 y^{2} = 144$

Step 2. Concept used

The standard form of the ellipse with Center at the origin is

$\frac{x^{2}}{a^{2}} + \frac{y^{2}}{b^{2}} = 1 a > b \Rightarrow majoraxisis x - axiswithendpoints (- a, 0),(a,0) b > a \Rightarrow majoraxisis y - axis.withendpoints ((0, - b),(0,b)$

Step 3.Find the center and major axis

$16 x^{2} + 9 y^{2} = 144 Given \frac{16 x^{2}}{144} + \frac{9 y^{2}}{144} = \frac{144}{144} Dividewith 144 onbothsides \frac{x^{2}}{9} + \frac{y^{2}}{16} = 1 Simplify$

Compare the given equation with the standard form of the ellipse

$Center:(0,0), 16 > 9 and a^{2} = 9 \Rightarrow a = \pm 3 b^{2} = 16 \Rightarrow b = \pm 4$

Major axis:

on y-axis with end oints $(0, - 4), (0, 4) .$

Minor axis:

Step 4. Sketch the graph

The graph of the ellipse is shown below
