Question

The given graphs show the relation between input and output. Which of the following graphs reprsents a linear function?

• A. Graph B
• B. Graph A
• C. Graph C
• D. Graph D

Answer 1

The correct option is D Graph D



Let us look at Graph A.

It is a curved line, so it does not represent a linear function.

For Graph B:

It is a curved line, so it does not represent a linear function.

For Graph C:

It is a curved line, so it does not represent a linear function.

For Graph D:

It is a straight line, so it represents a linear function.

So, only Graph D represents a linear function.
