Finding the Number of Solutions to Linear Equations: Using Tables and Graphs

This lesson teaches how to determine the number of solutions to a pair of linear equations using tables and graphs. It covers three examples: Amanda and Beatrice's parallel lines with no solution, Catlin and Devon's identical lines with infinitely many solutions, and Eric and Fran's intersecting lines with one solution. The lesson concludes by summarizing the conditions for no solution, one solution, and infinitely many solutions in linear systems.

What does it mean if the points in a table are always the same?

Describe the relationship between Eric and Fran's savings over time based on the provided data.

Summarize the conclusions that can be drawn about linear systems based on the examples given.
