Unit 7, Lesson 12
Interpreting Points in a Coordinate Plane
Accelerated 6
Preparation
Lesson Narrative
In this lesson, students pay attention to choices for what the axes represent and the scale used on each axis. Graphs need to present information clearly and legibly to be useful for visualizing relationships between quantities. Students begin by matching points plotted in the coordinate plane with their coordinates. They interpret the meaning of certain points in relation to a given situation and use inequalities to express relationships. They also reason abstractly and quantitatively as they interpret vertical distance in a coordinate plane in context (MP2).
- Compare points on a graph, including statements about relative position and the vertical distance between points.
- Describe (using words and inequality symbols) and interpret the range of coordinates on a graph, including the meaning of $y$-values that are negative.
- Identify and interpret points on a graph to answer questions about situations involving temperature or money.
Let’s examine what points in the coordinate plane can tell us.
