Answer:
Please check the explanation below.
Step-by-step explanation:
Note: As you forgot to mention the graphs of a linear function. But, let me clear your concept with an example of a linear function.
We know that linear function is of the form
y = mx+b
where
We know that the graph of a linear function is a straight line because the highest power of the exponent of the x variable is 1.
Thus, y = mx+b represents a straight line.
For example,
Let the linear function
y = 2x+3
comparing with the linear function of the form y = mx+b
As the highest power of the exponent of a variable is 1, therefore y = 2x+3 represents a straight line.
The graph of the linear function y = 2x+3 is also attached below.
