On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction the number b varies directly with the number a. for example b = 22 when a =-23. which equation represents this direc variation between a and b? b=-a -b=-a b-a = 0 b(-a) = 0
the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.
in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the x-axis .
12 + 5 = 17
