Question

describe the rate of change for this relationship.
the amount of paint kendrick uses increases by per rock.
\\(\frac{3}{8}\\) of an ounce
\\(2\frac{2}{3}\\) of an ounce
3 ounces
5 ounces
6 ounces
14 ounces

Explanation:

Step1: Identify two points on line

Choose points (0,0) and (6,4) from the graph.

Step2: Calculate rate of change

Rate of change = $\frac{\text{Change in paint (y)}}{\text{Change in rocks (x)}}$ = $\frac{4-0}{6-0} = \frac{4}{6} = \frac{2}{3}$

Answer:

The amount of paint Kendrick uses increases by $2\frac{2}{3}$ of an ounce per rock.
