Which of the following describes the graph of a linear function?
It is a curve that lies in only two quadrants
Its y-values decrease at a constant rate as its x-value increases
it is a straight line in one portion and a curve in another portion
its y-values increase at a non constant rate as its x-value increases.
I believe that the last one is correct because it is not a curve but a straight line, and it can't be the second one because the y value does not decrease as x increases
