Find the rate of change, (y2-y1)/(x2-x1), from the data given...
(2.16-1.26)/(12-7)=0.18
(1.26-0.72)/(7-4)=0.18
Since the rate is constant, this is a linear equation of the form y=mx+b. Furthermore, since 0 pencils cost 0, b=0, so the cost of the pencils is simply the number of pencils times 18 cents...
c(p)=0.18p (cost with respect to pencils is 0.18 times the number of pencils)

The total growth, in inches, of Isabella's plant is
inches
<h3>How to determine the total growth</h3>
From the line plot, the total growth can be represented as:

Evaluate the products

Evaluate the sum

Evaluate the numerator

Evaluate the quotient

Hence, the total growth, in inches, of Isabella's plant is
inches
