Question

# How can you use a function to represent a linear relationship?

Hint:

### Linear relationship is represented though a straight line.

## The correct answer is: by obtaining a straight line

### Linear function is a mathematical equation used to express a straight – line relationship between two variables.

This straight – line relationship is called linear relationship.

Firstly, put values of x in the given function and find y i.e. find at least 3 ordered pairs (x , y).

Now, locate the points on the graph and join them.

Though 2 points are sufficient to obtain a straight line, but its better to locate third point as well for justification or confirmation that it is a straight line.

Since we have obtained a straight line, it implies that the two variables have a linear relationship.
