Solve the problem.The population of an endangered species of fish were moved to a controlled habitat to encourage the species to increase in numbers. When they were moved there were 57 members in the population. In 18 months there were 147 members in the population, with a growth pattern that was approximately linear. Draw a graph that fits this data. On the graph, darken the part of the graph where the population is less than or equal to 100 members. Estimate, to the nearest month, how many months passed before the population reached 100.
