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.

What is the equation that represents Steven’s situation?

to find the equation calculate the slope of the pts.

You have two pts being (time, height) as A(0,2) and B(5,8)
The slope (gradient) is given by
$$\frac{ y2 - y1 }{ x2 - x1 }$$

Plug the two pts in to find the slope.

Afterwards pick ONE of the points, say A
and then sub it into this equation along with the gradient you just found

$$y - y_1 = m(x-x_1)$$

as the only difference between the answers is the slope you actually only really need the slope to answer this MCQ.
