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.
Answer:no because mixed numbers need atleast a one and a fraction to be mixed number but if there was a fraction then it couldnt equal two because of the 1's
Step-by-step explanation:
I believe it is the first one. A.
Answer:
Equation: 243+x=327
Answer to the equation: x=84
Step-by-step explanation:
First, subtract 243 from both sides of the equation, which would leave you with x=84, which is your answer.
I hope this helps! :)
