Facts about Linear Functions

In this math video we will learn facts about linear functions. We will discuss the characteristics of a linear function in slope-intercept form. We will review that slope-intercept form is y=mx+b. We will discover that m represents the slope of the linear function and b represents the y-intercept of the function. We will also understand that (0, b) is the point where the line crosses the y-axis. We will also be presented with 5 equations. We will determine which two represent a linear equation. We will review that a linear equation can be written in the form y=mx+b where the x variable has an exponent of 1. We will consider each equation, identify the exponent of the variable x and determine if the equation is linear. An exemplar solution is modeled and explained.
