Answer and Step-by-step explanation:
1st box:
0, -3
2nd box
-2, -9/4
3rd box:
2, -3/2
4th box:
4, 0
Btw 0, -2, 2, 4 are in the x-coordinate column if you didn’t know, and 1, -9/4, -3/2 are in the y-coordinate column
Basically to solve if you plug in 0 into x, so basically it’s 3(0)-4y=12, which you simplify gives you 0-4y=12, subtract 0 from 12 which is 12 and then do 12 divided by -4 and then you get y = -3 and that’s how you get the box answer
Idk how to the rest srry lol!
He would have bought 7 pound
This is because you would add 4 and 3 together
Hope this helps!
