9. choose all pairs of points that are
reflections of each other across
both axes.
(-3.5, 1) and (33, -1)
(5.4, -2) and (4.5,2)
(-12,3) and (1.25, -3)
(23, 4) and (4,2)
(2.5,3.5) and (-23, 32)

answer:

c. the third graph

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
