Question

If you are also able to explain this please do! I'd greatly appreciate it!

Answer 1

^ those are right and the 3rd one is -3 in case you can't get it.

2*-1=-2 -2-1=-3

Answer 2

You're given a table of x values and an equation. To solve, plug in the values for x.

First box: y=2(-3)-1=-7
Second box: y=2(-2)-1=-5.

See if you can solve the third one.
