I really need help with these two, I'd really appreciate an answer as soon as possible. (Questions in picture below)

2.$9.25  3.11

Step-by-step explanation:

For the first question virtually you could just go through each one and determine how they would fit. But what I did for both is determine the change in the first column (5 in #2 3 in #3) Then subtract the second change from the first in the second column (185-138.75 and 132-99) you come up with a rate of change like (46.25 and 33) then using that number dividing by the change from the first column (46.25/5=9.25 and 33/3=11) And to check applying all of that to the other changes.

correct answer:

b.(19,-2)
