Question

Eazzy math question!

Answer 1

OK, so to determine which table represents a linear function, you must remember that both the x values in the 1st column needs to have a constant rate of change and the y values in the 2nd column ALSO need to have a constant rate of change.

So the table on the top-left would be the correct answer (hopefully). Although the x-values go up by 1, the y values go up by 3, then 2, then 1, which does not fit with the requirement of have a constant rate of change.

The other three tables (which DO represent a linear function), have constant rate of change with the y-values: the top-right going up by 5; the bottom-left going up by 1; and the bottom-right going down by 3.
