We have been given that on a coordinate plane a line with negative slope passes through points and
. We are asked to find the rate of the change of the function.
We know that slope represents rate of change of function.
We will use slope formula to solve our given problem.
Let and
.
Therefore, the rate of change of the given function is .
The unit rate is 0.25 kilograms per year.
Step-by-step explanation:
Lets define unit rate first
Unit rate is the change in quantity per unit time.
Given
Weight = w = 5 kg
Time = t = 20 years
So,
Hence,
The unit rate is 0.25 kilograms per year.
