What you’ll learn
Graph relationships between variables.
Key idea
Each table column becomes one ordered point; the complete relationship includes every supplied column.
Keep x then y and include every table column; matching the intercept alone does not establish the rate or full relationship.
Worked example
Enter the exact value or ordered values in the format requested below.
Read the labeled relationship graph with x horizontal and y vertical. What y is plotted at x=5?
Marked coordinates: P=(5, 14); P=(1, 6); P=(0, 4).
- Pair each horizontal x input with its plotted vertical y output: ((0, 4), (1, 6), (5, 14)).
- Every point follows y=2x+4, including the intercept (0,4) and target (5,14).
Answer: 14
Quick Check
Relate the graph used in 'Graph relationships between variables' to an equation, table, transformation, or verbal description.
Connect the labeled graph to an equation explaining every point, including the point at x=2.
Marked coordinates: P=(2, 9); P=(1, 5); P=(0, 1).
