Chapter 9.3
Relationship between two variables
What You'll Learn
Distinguish between independent and dependent variables in coordinate systems
Identify domain (x-axis) and range (y-axis) on graphs
Understand ordered pairs and how to represent them as coordinates
Recognize the four quadrants and their locations on the coordinate plane
Plot points accurately using x and y coordinates
What You'll Practice
1
Creating mapping notation from sets of x and y values
2
Writing ordered pairs from given coordinates
3
Identifying which quadrant contains specific points
4
Plotting points on a coordinate grid using positive and negative values
5
Reading coordinates from points shown on a graph
Why This Matters
Understanding the relationship between two variables is foundational for all of algebra, geometry, and calculus. You'll use coordinate systems to graph equations, analyze data in science classes, and solve real-world problems involving relationships like distance over time or cost per item.
