1.11.6 Lesson Summary

In this lesson, you learned how to:

• Find the slope and vertical intercept of a line with equation $ax+by=c$.
• Take an equation of the form $ax+by=c$ and rearrange it into the equivalent form $y=mx+b$.
• Use a variety of strategies to find the slope and vertical intercept of the graph of a linear equation given in different forms.

Here are the activities that helped you reach those goals:

• 1.11.1: Applying the Distributive Property to Rewrite Expressions
  • In this activity, you rewrote expressions and discussed your strategies, including the distributive property.
• 1.11.2: Relating Two-Variable Equations, Their Graphs, and Situations
  • In this activity, you looked at two graphs from previous lessons and which numbers were slopes and intercepts. You also interpreted the meaning of those numbers in the situations graphed.
  • 1.11.2: Self Check
  • 1.11.2: Additional Resources
• 1.11.3: Reasoning Symbolically and Abstractly about Linear Equations
  • In this activity, you matched equations in standard form to their slopes and $y$-intercepts.
  • 1.11.3: Self Check
  • 1.11.3: Additional Resources
• 1.11.4: Identifying the Features of a Graph
  • In this activity, you used an equation to identify features of the graph of the equation including the slope and where the line would cross the $x$-axis and $y$-axis.

After these activities, you completed the following practice:
