- 8. Multiple ChoiceWhich equation matches the table below?y = -1/2 x - 4y = 1/2 x - 4y = 1/2 x + 4y = -1/2 x + 4
- 9. Multiple ChoiceWhat is the equation that matches this graph?y = -3/2 x - 1y = 3/2 x + 1y = -3/2 x + 1y = 3/2 x - 1
- 10. Multiple ChoiceWhich equation shows the number of bottles left after x days?
A family buys a case of water with 48 bottles and drinks 5 bottles per day.y = 48x + 5y = -5 + 48xy = -5x - 48y = 48 - 5x - 11. Multiple ChoiceWhich equation matches the table below?y = 3x + 6y = -3x + 6y = 3x - 6y = -3x - 6
