### Conclusion

In this chapter, you have explored how relations between domain and range values allow you to understand linear equations. In your explorations of linear equations, you generated lines that have slopes that do not change. A line with a slope of 2 maintained its slope for its entire length, which might have extended indefinitely. In contrast, you explored how lines for other types of equations, such as parabolas, do not maintain the same slope throughout.

In your exploration of linear functions, you used the line’s slope-intercept equation. This equation allowed you to bring the slope and y-intercept of a line into a formal relationship. If you assigned a negative value to the slope of an equation, you forced the line to slope downward ...
