Answer:
Each point (or pair in a proportional relationship) must share the same difference
Step-by-step explanation:
The graph of a proportional relation is a straight line through the origin. Such a line has the same ratio of y/x everywhere.
A relation in which the difference is constant will be a straight line, but it won't be through the origin. Such a relation is not proportional.

Answer:
xy = -1 and y = -1/x are the same.
They are not linear equations because they are not written in the form
Ax + By = C.
Quintet is what a stanza containing five lines is called.
Isolate the y to one side so we get: y = 2x - 1
The slope of the line is 2.
Double is double, so you can solve
.. 2 = 1*e^(.08t)
and get the correct value of t.
Taking logs,
.. ln(2) = .08t
.. ln(2)/.08 = t ≈ 8.7 . . . . years
