How are lines generated by addition rules different than lines generated by multiplication rules? Are they different? Find out by joining Mrs. LaFont as she identifies rules when given a coordinate pair, generates coordinate pairs and constructs lines. We will take note of the differences in the lines we construct. For this lesson, you will need a pencil, a straightedge, the lesson 10 template and the lessonâs Problem Set. You can access the lesson 10 template and the lessonâs Problem Set using the link below.
