Tap for more steps...

Step 1.1.1

Subtract

h (x)

$h (x)$ from both sides of the equation.

y - h x = 2

$y - h x = 2$

Step 1.1.2

Reorder

y

$y$ and

- h x

$- h x$ .

- h x + y = 2

$- h x + y = 2$

- h x + y = 2

$- h x + y = 2$

Step 1.2

Divide each term by

2

$2$ to make the right side equal to one.

- \frac{h x}{2} + \frac{y}{2} = \frac{2}{2}

$- \frac{h x}{2} + \frac{y}{2} = \frac{2}{2}$

Step 1.3

Simplify each term in the equation in order to set the right side equal to

1

$1$ . The standard form of an ellipse or hyperbola requires the right side of the equation be

1

$1$ .

\frac{y}{2} - \frac{h x}{2} = 1

$\frac{y}{2} - \frac{h x}{2} = 1$

\frac{y}{2} - \frac{h x}{2} = 1

$\frac{y}{2} - \frac{h x}{2} = 1$

Step 2

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

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

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

Step 3

Match the values in this hyperbola to those of the standard form. The variable

h

$h$ represents the x-offset from the origin,

k

$k$ represents the y-offset from origin,

a

$a$ .

a = \sqrt{2}

$a = \sqrt{2}$

b = \sqrt{2}

$b = \sqrt{2}$

k = 0

$k = 0$

h = 0

$h = 0$

Step 4

The center of a hyperbola follows the form of

(h, k)

$(h, k)$ . Substitute in the values of

h

$h$ and

k

$k$ .

(0, 0)

$(0, 0)$
