A proportional relationship can be written as an equation in the form ____ = _____  _____

• y = k+x
• y = k-x
• y = kx
• y = k/x

Write an equation for this relationship.

• y=18x
• y=18.50x
• y=22.50x
• y=22x

What is the equation that represents this relationship?

• y = 1/4x

• y = 1/2x

• y = 2x

• This is not a proportional relationship.

What is the equation that represents this relationship?

• y = 1/12x

• y = 12x

• y = 0.6x

• This is not a proportional relationship.

What is the equation that represents this relationship?

• y = 1/3x

• y = 3x

• y = 2/3x

• This is not a proportional relationship.

Write the equation for the table.

• y = x + 4
• y = 5x
• y = 4x + 1
• y = x + 5

• y = 2x = 15

• y = 15x +2

• y = -15x

• y = 15x

• y = 2x + 75

• y = 75x

• y = -75x

• y = 75x + 2
