There are 3 sets of cards that students will match together. With set 1, students will find the slope of a line passing through 2 points. In set 2, students will manipulate linear equations to identify the slope. Students will then match the cards in set 1 that are parallel to set 2. Set 3 has a mixed methodology for finding slope but all lines are perpendicular to the lines in sets 1 and 2. Students will match the cards in set 3 with the corresponding perpendicular lines in sets 1 and 2.
