For 1 and 2, use Function, Insert Relation
-------------
To do them manually, as you'd have to do on a test:
Solve for y
x^2/16-y^2/25=1

Pick values for x and solve for y. Remember + and minus values, too.
eg
x y
4 0
-4 0
5 15/4
-5 15/4 etc.
--------------
Plot the points (4,0), (-4,0), 5,15/4) etc
