A red-throated loon is a type of diving bird that dives for its food. One particular loon dives for 8 seconds to a depth of 12 feet under the surface of the water. a. Assume the loon dives at a constant rate. Write an equation that can be used to represent the elevation, y, of the loon after x seconds into the dive. b. If the loon is at a depth of 22 feet under the surface of the water, how long was it diving for? Show your work.
