The first four terms of a sequence are shown on the graph below. On a coordinate plane, points are at (1, 5), (2, 10), (3, 15), (4, 20). What can be concluded about the sequence? The slope of the graph is 1. The slope of the graph is 5. The equation f (x) = 5 Superscript xrepresents the sequence. The equation f (X) = 4 x + 1 represents the sequence.
