Question

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=56x+2

y=85x+2

y=58x+2

y=65x+2

sort ansers please

Answer 1

• D. y = 6/5x + 2

Explanation:

• Initial height is 2 in
• Height after 5 weeks is 8 in

Rate of change is

• (8 - 2)/5 = 6/5

So the equation is:

• y = 6/5x + 2

Correct option is D
