Add more points on the graph ... and it still remains a line! The 13th installment in a series of 33 leads the class to the understanding that the graph of linear equation is a line. Pupils find several solutions to a two-variable linear equation and plot them on the coordinate plane. They determine what the shape of the graph appears to be and verify by adding more solutions to the graph.

Instructional Ideas
- Use graphing software to graph distinct points of a variety of types of equations to compare to linear equations
Classroom Considerations
- Class members should be able to solve equations in one variable
- The class should be familiar with the coordinate plane
Pros
- The answer key shows the steps needed to solve the equations
- Questions require the scholars to justify their answers
Cons
- The lesson does not exactly match the standard since the graphs are not proportional relationships
