Steps to Construct a Linear Function

Write an equation for the cleaning cost, y, for the number of hours, x. Put in y = mx + b form.

• y = 12x + 20

• y = 20x + 8

• y = 8x

• y = 8x + 20

Write an equation in y = mx + b form for the cost, y, to belong to the gym for x months.

• y = 35x + 40

• y = 40x + 35

• y = 35 x + 70

• y = 75x

Write an equation in y = mx + b for the movie membership above.

• y = 15x + 5

• y = 5x + 15

• y = 5x + 40

• y = 12x + 75
