What is always true when two whole numbers are subtracted?

Given the following linear function sketch the graph of the function and find the domain and range. ƒ(x) = -5x + 4

For a short time after a wave is created by wind , the height of the wave can be modeled using y= a sin 2pi(t) / t where a is the amplitude and t is the period of the wave in seconds. how many times over the first 5 seconds does the graph predict the wave to be 2 feet high?
