Slope-Intercept Application

Which value is the slope in the equation:

y= 4x + 2

• 4

• 2

• x

Which value is the y-intercept in the equation:

y= 2x -2

• 2

• -2

• 1

Write the equation for the line in slope-intercept form.

• y= -1x+3

• y= 4x+3

• y=1/4x+3

• y= -4x+3

Write the equation of the line.

• y= -1x-3
• y= -3x-1
• y=-1/3x-1
• y= -3x-3

Which is the graph of y=-x+2?

• A
• B
• C
• D

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

Belinda's car needed repairs. The mechanic charged him $140 for the parts and an additional $48 an hour for labor. Write an equation that models this situation.

• y = 140x +48

• -48x +140y=0

• y = 48x +140

• y = 48x

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 pizza shop charges $12 per pizza and a delivery fee of $4.

Which equation represents the cost, c, for any number of pizzas, p?

• c = 4p + 12

• c = 12p + 4

• c = 16p

• p = 12 + 4 + c

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
