• y= -1x+3

• y= 4x+3

• y=1/4x+3

• y= -4x+3

Write the equation of the line.

• y= -1x-3

A driving range charges $4 to rent a golf club plus $2.75 for every bucket of golf balls you hit.

Write an equation that shows the total cost c of hitting b buckets of golf balls.

• c = 2.75b + 4

• c = 2.75b

• c = 4b- 2.75

• 2.75b - 4c = 6.75

A real estate agent earns a base salary of $1250. For every house, h, she sells, she receives $750.

Which equation could be used to determine the amount of money, m, she would have after selling any number of houses, h?

• m = 1250 + 750h

• m = 750 + 1250h

• 1250 = 750h + m

• 750 = 1250m + h

A car rental company charges $56 plus $0.30 per mile driven.

Write a linear function to model this situation.

• y = 56x + 0.30

• 56x + 0.30y = 86

• y = 0.30x + 56

• y = 56 - 0.30x
