Steven recorded the growth of a plant over 10 weeks for his science project. He made a graph that shows how much the plant grew each week. The plant was 2 in. tall when Steven started his project. At week 5, the plant was 8 in. tall. Which equation represents Steven’s situation, where x is the number of weeks and y is the height of the plant?

y=65x+2

y=56x+2

y=58x+2
