Question

HELP I HAVE A TIMER!!!! Which table represents a linear function?

Answer 1

Answer:

A (first option from the left)

Step-by-step explanation:

The y values of a linear function should increase/decrease by a direct amount that DOESN'T change.

Let's evaluate each answer choice to show you what I'm describing:

Answer Choice A:

As x increases by 1, the y value increases by a direct amount of 1/2. This is why this answer is correct.

Answer Choice B:

As x increases by 1, x first decreases by 1/2, then 1/6, then 1/12. See how the amount being decreased changes? This answer is wrong.

Answer Choice C:

As x increases by 1, x first increases by 2, then 4, then 8. The amount being increased continues to change, so this answer is wrong.

Answer Choice D:

As x increases by 1, x first increases by 6, then 10, then 14. The amount being increased keeps changing, so this answer is wrong.
