Understanding First-Degree Functions

The video tutorial introduces linear functions, explaining their definition and the role of coefficients. It demonstrates how to identify coefficients and graph linear functions using two points. The tutorial also covers the properties of linear graphs, including their intersections with axes. The video concludes with a summary and encourages viewers to continue learning through additional videos.

What is the general form of a first-degree function?

• y = a + bx^2

• y = a/x + b

• y = ax + b

• y = ax^2 + bx + c
