Activity Overview
In this activity, students will use coordinates to better understand that relationship, as well as the relationship between coordinates of points and their quadrant locations, slopes and y-intercepts, and parallel and perpendicular lines.
Objectives
- Students will graph linear functions and determine properties such as slope and y-intercept, describe how both change as the graph is rotated and translated, and understand that the coordinates of a line are the solution set to the equation of the line.
- Students will show that lines with equal slopes are parallel and slopes that are negative reciprocals are perpendicular.
- Students will try to make a connection with how to understand these topics in IB Mathematics courses and on their final assessments
Vocabulary
- Parallel
- Perpendicular
- Reciprocal
- Slope
