Candles for making a movie

Ana is making a movie. She is filming a fancy dinner scene and she has two types of candles with the data included in the task image. She wants to determine how long the candles will last. She takes a picture, lights the candles, and then lets them burn for 1 hour. She then takes a second picture. You can assume that each candle burns at its own constant rate. The height of each candle Ana uses, h, corresponds to a linear function that depends on the time, t, following the equation h = k + nt What do the parameters k and n represent in the equation h = k + nt?
