General Formulas and Concepts:

Algebra I

• Linear - Any degree of 1 in the form of y = mx + b or Ax + By = C
• Nonlinear - Any degree higher than 1

Explanation:

Step 1: Define

y = 2x + 3

Step 2: Identify

We see we have a linear equation in y = mx + b. We can also see that it is a degree of 1. Therefore, it is a Linear proportional relationship.
