$\frac{x^{2}}{49} - \frac{y^{2}}{12} = 1$

Step 1

Simplify each term in the equation in order to set the right side equal to $1$ . The standard form of an ellipse or hyperbola requires the right side of the equation be $1$ .

$\frac{x^{2}}{49} - \frac{y^{2}}{12} = 1$

Step 2

This is the form of a hyperbola. Use this form to determine the values used to find the asymptotes of the hyperbola.

$\frac{{(x - h)}^{2}}{a^{2}} - \frac{{(y - k)}^{2}}{b^{2}} = 1$

Step 3

Match the values in this hyperbola to those of the standard form. The variable $h$ represents the x-offset from the origin, $k$ represents the y-offset from origin, $a$ .

$a = 7$

$b = 2 \sqrt{3}$

$k = 0$

$h = 0$

Step 4

The asymptotes follow the form $y = \pm \frac{b (x - h)}{a} + k$ because this hyperbola opens left and right.

$y = \pm \frac{2 \sqrt{3}}{7} x + 0$

Step 5

Simplify $\frac{2 \sqrt{3}}{7} x + 0$ .

Step 5.1

Add $\frac{2 \sqrt{3}}{7} x$ and $0$ .

$y = \frac{2 \sqrt{3}}{7} x$

Step 5.2

Combine $\frac{2 \sqrt{3}}{7}$ and $x$ .

$y = \frac{2 \sqrt{3} x}{7}$

Step 6

Simplify $- \frac{2 \sqrt{3}}{7} x + 0$ .

Step 6.1

Add $- \frac{2 \sqrt{3}}{7} x$ and $0$ .

$y = - \frac{2 \sqrt{3}}{7} x$

Step 6.2

Combine $x$ and $\frac{2 \sqrt{3}}{7}$ .

$y = - \frac{x (2 \sqrt{3})}{7}$

Step 6.3

Move $2$ to the left of $x$ .

$y = - \frac{2 x \sqrt{3}}{7}$

Step 7

This hyperbola has two asymptotes.

$y = \frac{2 \sqrt{3} x}{7}, y = - \frac{2 x \sqrt{3}}{7}$

Step 8

The asymptotes are $y = \frac{2 \sqrt{3} x}{7}$ and $y = - \frac{2 x \sqrt{3}}{7}$ .

Asymptotes: $y = \frac{2 \sqrt{3} x}{7}, y = - \frac{2 x \sqrt{3}}{7}$
