Answer

This statement is not correct.

Step-by-step explanation

Not every straight line is a graph of a function.

Although, nearly all linear equations are functions because they pass the vertical line test. That is, most linear equations are set up that you can obtain a value for y, given a value for x.

Examples of linear equations that are functions include

y = 10

y = x

y = 2x

y = 7x + 14

y = − 2x − 7

The exceptions are relations that fail the vertical line test. The ones that don't give a y-value for every x.

Examples of linear equations that are not functions include

x = some constant

That is,

x = 7

x = -100 etc.

Hope this Helps!!!
