1.1 Relationship between two variables
Relationship Between Two Variables
A relationship between two variables shows how the dependent variable changes as the independent variable changes.
What You'll Learn
A relationship shows how a dependent variable (y) responds to an independent variable (x).
A table pairs each x-value with its matching y-value.
Plotting the pairs and connecting them turns a table into a graph.
If the plotted points form a straight line, the relationship is linear.
A relationship can be read both ways: from x to y, or from y back to x.
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.
