What is the rate of change

The rate of change is 1

Step-by-step explanation:

In order to calculate the rate of change, take two points (in this example I'll use points (8, 2) and (10, 4)) and input them into this expression used to calculate rate of change:

Solve:

4 - 2 = 2

10 - 8 = 2

2/2 = 1

The rate of change is 1.

Hope this helps :)

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
