Compare the two linear functions listed below and determine which has a greater slope.

• Function 1 because the slope is 3/2

• Function 2 because the slope is 1

• Function 1 because the slope is 2/3

• They are equal 

Compare the two linear functions listed below and determine which has a greater slope.

• Function 1 because the slope is 12

• Function 2 because the slope is 1

Lee charges $3 for a basket and $2.50 for each pound of fruit picked at the orchard. Write an equation in y = mx + b form for the total cost of x pounds of fruit from the orchard.

• y = 3x + 2.5

• y = 2.50x + 3

• y = 2.50x 

• y = 3x + 2.50

You plan to go snowboarding. The resort charges $15 an hour in addition to $25 to rent a board. Write an equation that represents the cost to go snowboarding for the day.

• y=15x-25

• 15x+25y=100

• 25x+y=15

• y=15x+25
