• y = 4/3 x - 1

• y = 3/4 x - 1

What is the equation for this graph?

• y = 4/3 x + 1

• y = -4/3 x + 1

• y = 4/3 x - 1

• y = -4/3 x - 1

What is the equation for this graph?

• y = -⅕ x - 2

• y = -5x - 2

• y = ⅕ x - 2

• y = 5x - 2

What is the equation for this graph?

• y = -3/7x + 4

• y = -7/3x + 4

• y = -3/7x + 10

• y = -7/3x + 10

At Joe's Clown Car Rental Agency, renting a car costs $35 plus $0.75 for every mile it is driven.  What is an equation that can be used to find the number of miles, m, a vehicle was driven, if the total rental charge was $222.50?

• 222.5 = m(35 + 0.75)

• 222.5 = 35 + 0.75m

• 222.5 = 0.75 + 35m

• 222.5 = 0.75(m + 35)

A holiday meal cost $12.50 a person plus a delivery fee of $30. Which equation represents the amount a holiday meal costs(y), including delivery, for x people?

• y = 12.50 + 30x

• y = 30 + 12.50x

• y = 12.50 + 30

• 12.50x = 30
