2. y = x – 10

3. y = –x – 10

4. y = 10 + x



PLS help!!!

Answer 1

Answer:

1. y = 10 - x

Step-by-step explanation:

Because he starts off with 10 dollars, and x is the amount he spends on an item, y is showing the change that he would get from paying with a 10 dollar bill, so it's what's left over from that 10 dollars.
