The diameter of a Douglas fir tree is currently 10 inches when it is measured at chest height. After 50 years, the diameter is expected to increase by an average growth rate of 2/5 inch per year. The equation y = (2/5)x + 10 gives y, the diameter of the tree in inches, after x years. Draw a graph of the equation. Describe the relationship.
