Suppose you are given the formula (y+3)/4 = ± (x+2)/9 for the asymptotes of a hyperbola. What is the formula for the hyperbola?
Specifically, can you tell how this hyperbola opens? Can you tell if it opens up-down, or to the sides?

In highschool, I've taken Algebra, Algebra 2, Advanced Mathematics, Analytical Geometry and College Algebra. Now I'm taking Precalculus at a community college, and I've found that this and every other math I've taken above are the same (with the exception of increased difficulty as I progressed from one to the next). Am I delusional, or are they really just the same math with different names?

Here is the exact question...

Represent this situation on graph paper. You're behind a truck that is 30 feet in length, and 14 feet tall. A traffic signal is directly above the front of the truck, 18 feet above the ground. How far behind the truck are you if you can just see the signal, if your eye is 4 feet above the ground?

anybody have any ideas on how to solve this??
