All Tasks - Asymptote

Cross for the following relations if they are based on a proportional relation.

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?

Find the rate of change of the graph in the image. Include units (inches/second)

Determine the slope of a linear function which is parallel to the line $(ε)$?

After solving a main task, sometimes a hidden task appears. Solve the "fill in the blanks" below to explore such a challenge task.

The graph of the photo has the formula $(ε):\ y=3x-4$. Which of the following points does the linear function pass through?
