Algebra 19 - Linear Equations y = mx

Professor Von Schmoke introduces real-valued functions and their representation on the Cartesian plane. The video explains linear functions, their equations, and how they are graphed. It discusses the role of coefficients in determining the slope of a line, including positive and negative slopes. The video also covers horizontal and vertical lines, emphasizing the relationship between coefficients and graph slopes.

How can you verify if a point lies on the graph of a linear function?

In what way does the magnitude of the coefficient affect the slope of a linear function?

What is the difference between a function that describes a line and one that describes a vertical line?
