Coordinates, Lines & Graphs
An equation in two quantities describes coordinate pairs that satisfy a relationship, and slope measures a rate linking horizontal and vertical change.
What you'll learn
- Read and plot ordered pairs with horizontal coordinate first.
- Interpret a graph as the set of coordinate pairs satisfying a relationship.
- Compute slope as vertical change divided by matching horizontal change.
- Attach meaningful units to slope in context.
- Distinguish a relationship's numerical slope from its apparent steepness under changing axis scales.
