Students graphed the growth rate over several weeks of two plants in their classroom. The equations of both plants
are given where x represents the time in weeks and y represents the heights of the plants in inches.
Plant A. y = 1.8x + 3.1
Plant B y = 2.3x + 1.9
Approximately how many weeks will it take for both plants to reach the same height? Round your answer to the
nearest tenth
O 1.9 weeks
2.4 weeks
O 3.1 weeks
O 7.4 weeks
