Answer: Good afternoon fellow student, to answer your question

y - 35 = 2(x - 10)

Explanation:

Let

y-----> the height of the plant

x ----> the number of days

Find the slope

we have the points

(10,35)

The slope is equal to

m= (55-35)/(20-10)

m= 2

Find the equation of the line into point slope form

y- y1 = m(x - x1)

we have

m= 2 and point (10,35)

y - 35 = 2(x - 10)
