I believe it would be the last table.

Step-by-step explanation:

A linear function has an equation of y=Mx+b where y and x are the variables but m (the slope) and b are constants. The slope for the last table is - 8 as the y values are decreasing by 8 every time you move forward one in the x axis. None of the other tables have a constant slope which means they don't have straight lines when you graph them. Therefore, the last table would have to be the only one representing a linear function
