What does the Direct Variation Equation look like?

• y= kx
• y = mx + b
• y = b
• y = x

What is the constant (k) in this inverse variation?
y = 400/x

• x
• y
• 400
• Not enough information given

Which of the following is NOT a direct variation?

• y = -2x
• y = 1/2x
• 2x + 3y = 2
• 3y = 4x

What is the equation for a Joint Variation?

• y = kx

• y = k/x
