A scientist planted seeds in 4 sections of soil for an experiment. Not all of the seeda grew into plants. After 20 days, the scientist counted the number of plants in each of the 4 sections. The results are as ahown in the table. Section 1 , sq ft 25, #of plants planted 13. Section 2, SQ ft 100 number of plants planted 38. Section 3, Sq ft 125, # of plants planted 47. Section 4, sq ft 150, # of plants planted 62. Use the data to determine approximately how many plants grew per sq ft. Explain or show how you determined your approximation. Let y be the number of plants expected to grow in x sq ft. Write an equation the scientist could use to model the relationship between y and x.
