What is the largest factor that can be factored out?

After 4 hours, a candle is 3 inches long. After 6 hours, it is 2 inches long. What's the equation for this problem?

  y = (-1/2)x + 3 y = (-1/2)x + 5 y = (1/2)x + 4 y = (1/2)x + 5

A brand new candle is 12 inches long. After 3 hours, it is 10 inches long. What's the equation for this problem?

  y = 3x + 2 y = (-2/3)x + 10 y = (-3/2)x + 12 y = (-2/3)x + 12 y = (2/3)x + 12
