## Best answer for which table represents a linear function

Only the first table represents a linear function.

Solution-

In order to be in linear function, the graph of the function 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 constant 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 the y.
