I don’t see the four tables in your message. I can’t pick which table(s) fit each description until you paste or describe them.

While you add them, here’s how to check each question so you can quickly identify the answers:

A. Not a function — check input (x) values: if any input repeats with two different outputs, the table is not a function.

B. Linear relationship — compute the rate of change Δy/Δx between successive rows (or any pairs). If the rate of change is the same for all pairs, the relationship is linear (can be written y = mx + b). Note: any table with only one or two distinct input values is automatically linear.

C. Decreasing relationship — if the rate of change (slope) is negative (y decreases as x increases) for every pair, the relationship is decreasing.

If you paste the four tables (or describe the rows for each), I’ll label which table(s) belong in A, B, and C.
