This video lesson by eMathInstruction covers non-proportional linear relationships in Algebra 1. It begins with an introduction to proportional relationships, explaining their characteristics and how they differ from non-proportional ones. The lesson then focuses on graphing linear functions using the slope-intercept form, providing examples and exercises to illustrate these concepts. The video concludes with a summary and review of the key points discussed.

What is a key characteristic of a proportional relationship when graphed?

• It passes through the origin.

• It has a negative slope.

• It forms a parabola.

• It intersects the y-axis at a non-zero point.
