Answer to Which table represents a linear function?
Only the first table represents a linear function.
Solution:
To be able to maintain linear function, the graph of the event must be a straight line.
Plotting the graph, by taking the data points from the given table and then plotting in the cartesian coordinates system, several graphs are generated. Among them only the 1st table, yields a straight line with a continuing slope.
So, the 1st table represents a linear function, where x and y are in direct proportion with positive slope, hence when x increases, so does they.
