- 1. Multiple Choicey = 2.50x + 2.65y = 2.65(x + 2.50)y = 2.65x - 2.50y = 2.65x + 2.50
- 2. Multiple Choicey = 5xy = x + 5y = x + 470y = 94x
- 3. Multiple Choicey = 2x + 12y = 6x + 4y = 2x + 4y = 4x + 6
- 4. Multiple Choice
Which table represents the equation y = 0.5x + 14?
A
B
C
D
- 5. Multiple Choice
Which equation below represent the graph?
y = -0.02x + 2,500
y = -500x + 8,000
y = 500x + 8,000
y = 0.02x + 2,500
- 6. Multiple Choicey = 3x + 3y = 3x - 1y = 1/3x + 3y = 1/3x - 1
- 7. Multiple Choice
Which statement below is supported by the graph?
Sarah earned $10 for every hour she babysat
Sarah earned $10 for babysitting and $1 extra for every hour
Sarah earned $10 more than the number of hours she worked
Sarah earned $10 for babysitting
- 8. Multiple ChoiceThe table shows the admission price to the school football game.
Which equation describes the total admission (t) for the number of people (p)?t = 6pp = 6t6p = t6t = p - 9. Multiple Choicey = x + 4y = 3xx = y + 4x = 3y
- 10. Multiple Choicey = 3xy = x - 3y = xy = x + 3
- 11. Multiple ChoiceABCD
- 12. Multiple ChoiceWhat is the equation?y=-2xy=-½Xy=-2x+4y=2x
- 13. Multiple ChoiceWhat is the equation?y=2x+4y=-2x+4y=2x-4y=-2x-4
- 14. Multiple ChoiceIs this a proportional equation? Why?It is not proportional because it doesn't have a constant.It is not proportional because it doesn't have a constant rate of change.It is proportional because if x = 0, y = 0.It is proportional because it has a y intercept.
- 15. Multiple ChoiceDoes this graph represent a proportional relationship?No, because it doesn't pass through the origin.Yes, because it doesn't pass through the origin.Yes, because it intersects the y axis.No, because it intersects the x axis.
- 16. Multiple ChoiceA local donut shop charged $6.50 for a dozen and provided a coupon in the newspaper for $0.75 discount. What is the equation that represents the value of a customer's order who uses the new coupon with their order?y = 6.50x - 0.75y = 6.50x + 0.75y = 6.50x - 1.50 - 0.75y = 5x - 0.75
- 17. Multiple ChoiceRandy charges his tenants $425 each month to rent his houses plus $600 security deposit. What equation best represents how much his tenants will now have to pay?y = 425x + 600y = 425 + 600xy = 400x + 625y = 400 + 625x
- 18. Multiple ChoiceWhat is the constant of proportionality?51/561
- 19. Multiple ChoiceWhat is the constant of proportionality?1557525
