Find the rate of change demonstrated in the graph below.

What is the answer to this?

4.5

Step-by-step explanation:

Formula for calculating slope can also be used in finding the rate of change of the given graph above.

Rate of change =

Take the coordinates of any two points on the graph. Let make use of (2, 9) and (4, 18).

Thus,

Rate of change =

Rate of change demonstrated in the graph is 4.5 miles per hour.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.
