Answer to Problem 32HP
The given statement is always true.
Explanation of Solution
Given information :
The given statement: “A linear relationship that has a constant rate of change is a proportional relationship”
A rate of change is a rate that describes how one quantity changes in relation to another quantity. In a linear relationship, the rate of change between any two quantities is the same, or constant, called the constant rate of change.
Thus, on increasing or decreasing one of the quantities the other quantity increases or decreases at a constant rate. Hence, a linear relationship that has a constant rate of change is always a proportional relationship.
