7. D

8. A

9. C

10. B

Step-by-step explanation:

You can use process of elimination to solve these problems easily.

Look at the chart and look at the x's and y's.

For #7, we can see table D would be the correct table because when you plug 0 into the equation, the result (y) is equal to 4.

7. D

For #8, if we plug in the x-values from table A, we can see that the output (y) is the same. For Ex, when you plug -3 into the equation, -3 - 7 equals -10, which corresponds to the table.

8. A

For #10, We can see that table B would be the correct table. You can verify this by plugging in -1 into the equation, the result is 4. -3(-1) + 1 = 4.

10. B

This leaves us with #9 matching up with table C.

9. C
