Question

Calculate the rate of change for the following data:A) -6B) 2C) 12D) 4

Answer 1

You have to use the formula of the rate of change in algebra

`(Δy)/(Δx)=(y_2-y_1)/(x_2-x_1)`

Now take 2 points, whatever you want:

I will take (2,5) and (7,25)

Now replace and solve:

`(y_(2)-y_(1))/(x_(2)-x_(1))=(25-5)/(7-2)=(20)/(5)=4`

The answer is 4, you can take any other points and prove that are always fulfilled.
