Answer:
a horizontal line
Step-by-step explanation:
The hyperbola opens vertically, so the directrix is a horizontal line (a different one for each branch).
The standard form for an equation is y=mx+b. You find the slope by using the formula of rise over run. This means that for problem 6 you first look to see if its positive or negative slope. The slope is positive if the line is going uphill and if its going downhill its negative. The slope would be negative for number 6 because it is going downhill. Then for the actualy slope you would start with rise. So you look at the point (0,1) and go up 3 until you hit the line of the other point and run over 2. So your slope would be -3/2.
Answer: Undefined
Step-by-step explanation:
slope is undefined
no y intercept
This line is vertical
