An anchor chain has 32 links lying on a ship's deck, while the rest of the chain is below deck height. Each time the raise-anchor control is activated, 9 more links come over the edge to lie on the deck

Write a linear function that models the number of chain links on deck after n activations of the raise-anchor control.

*HINT:

Common difference is the slope (m)
Initial value is the y-intercept (b)
