Direct and Inverse Relationship

• What does direct relationship mean?

  As one variable increases/decreases, the other increases/decreases at the same rate.
• What is the equation for direct relationship?

  y = kx
• What is the equation to get K for direct relationship?

  k = y/x
• What is inverse relationship?

  When one variable increases, the other decreases at the same rate vice versa
• what is the equation for inverse relationship?

  y = k/x
• What is the equation to get constant of proportionality for inverse relationship?

  k = xy
