Note 2

In the case of the asymptote, the slope of the line b/a is the square root of the number under the y2 divided by
2
the square root of the term under the x term.

Example 20—

Sketch and label x /7 - y /11 = 1.

Transverse vertices: y = 0, Note that if x = 0, , which are imaginary. The curve
does not hit the y axis. . Foci: .
