Concept

Objective: Students will determine slope from graph points and interpret what it means.

Estimated Time: 12 minutes

Standards:
HSF-IF.B.6HSF-IF.C.7

Slope quantifies steepness: positive slopes rise, negative slopes fall, zero slope is horizontal, undefined slope is vertical.

Try it

Find the slope of a line through (2, -1) and (6, 7).

๐Ÿ“ˆ Coordinate Grapher

Adjust slope and compare how steepness changes.
