The table below represents a function. x12345y612182430 Which statement would best describe the graph of the function?

As x increases by 1 each time, y increases by 6 each time: 6, 12, 18, 24, 30. A constant rate of change means the graph is a straight line, and its slope is 6. So the best description is “The graph is a straight line that has a slope of 6.”
