Calculator use is allowed on these questions, so use it wisely.

Based on the chart above, which of the following could express the relationship between $x$ and $y$ ?

Plug in the values from the chart. Use the pair $(-3,-7)$ from the top of the chart and eliminate answers that are not true: Choice (A) becomes $-7=-3-4$, which is true. Keep it. Keep (B): $-7=2(-3)-1$ is true. Get rid of $(\mathrm{C})$, which becomes $-7=2(-3)+2:-7$ does not equal $-4$. Get rid of (D): $-7=3(-3)-3.-7$ does not equal $-12$. Now use another pair just to test (A) and (B). Using $(-1,-3)$, (A) gives $-3=-1$ $-4$, which is not true, so eliminate it, leaving only (B). The values ( $-$ $1,-3)$ work: $-3=2(-1)-1$
