Answer:
Rate of change for the linear relationship modeled is 
Step-by-step explanation:
As the there is a linear relationship in the points, so all these points will be on a single straight line. Hence the slope will be same throughout all the points.
We know that, the slope of the line joining (x₁, y₁) and (x₂, y₂) is,

Putting the points as (-1, 10) and (1, 9), we get



Rate of change is the slope of the line joining all these points.
60%; Since 1/5 is .2 or 20% and then multiply that by 3.
Answer: The question isn't finished.
Step-by-step explanation:
Answer:
- 15, - 16
Step-by-step explanation:
-15 + (-16) = - 15 - 16 = - 31
I think The answer would be A
