Question
Which of the following statements is correct? 0 A. The relationship between two variables is linear when it is represented by a curved line and nonlinear when it is represented by a straight line O B. The relationship between two variables is nonlinear whether it is represented by a straight line or by a curved line O C. The relationship between two variables is linear when it is represented by a straight line and nonlinear when it is represented by a curved line. O D. The relationship between two variables is linear whether it is represented by a straight line or by a curved line.Explanation / Answer
Option c is correct.
The relationship between two variables is linear when if it is represented by a straight line and non linear when it is represented by a curved line.
A linear relationship can be represented by a straight line while there are two types of linear relationships, positive linear and negative linear.
If any two variables either increases or decreases at a constant rate they are said to be positive linear.
And if one of the variable increases and the other decreases at the same time, they are said to be negative linear.
Two variables are said to be non linear, if the rate in which one variables change affects the rate of increase or decrease, which leads to a curved data pattern.
