What is a linear relationship?

Looking at the word "linear" notice that it begins with "line."

A linear relationship is a relationship which can be represented by a straight line.

Let's look at an example of a linear relationship.

The perimeter of a square depends on the length of a side.

Perimeter = S + S + S + S = 4s

We can also write this in function notation as P (S) = 4s

Since we have one variable "s" and it's raised to the power of 1, this is a linear relationship.

Answer: Example

Step-by-step explanation:

None are squared or cubed or taken to any power. And also, none of the variables will be in the denominator. These are examples of equations that do not have a linear relationship ... The equation must graph as a straight line. Linear relationships such as y = 2 and y = x all graph out as straight lines.
