Hi!
Linear functions have a continuous pattern. Let's see which one of these tables has a pattern.
Choice 1: No Pattern
Choice 2: There is a Pattern
Choice 3: No Pattern
Choice 4: No Pattern
So, Choice 2 is a linear function. If you plot the points and graph the function, you'll have a line.
The graph of a linear function is always a line.
I hope it helps!
