Answer:
Step-by-step explanation:
The formula of the directrices are:
A relationship between the hyperbola constants is derived from the absolute value of the slope of the directrix:
The location of the foci indicates that hyperbola is vertical and centered at origin. The distance between foci is equal to . Then, the vertical parameter is:
One of the hyperbola coefficients is determined with the help of the Pythagorean Theorem:
The remaining parameter is found by means of the relationship described previously:
Lastly, the equation of the hyperbola in standard form is:
