You know the equation for hyperbola?

3. anonymous

nope

4. anonymous

The general form of hyperbola equation looks like this $\frac{ x^2 }{ a^2 } - \frac{ y^2 }{ b^2 }$

|dw:1438241576959:dw|

6. anonymous

just count the values for a & b then you can form the equation

7. anonymous

x^2/4 - y^2/9 =1 ?

8. anonymous

yup $\frac{ x^2 }{ 2^2 } - \frac{ y^2 }{ 3^2 } = 1$

9. anonymous

ty. what are vertices? that's my next question

10. anonymous

The a or -a are your vertices

11. anonymous

(-2,0) and (2,0)
