Characteristics of Linear Relations Lesson #3
Slope of a Line Segment
- The slope of a line segment is a measure of the steepness of the line segment.
- It is the ratio of rise (the change in vertical height between the end points) over run (the change in horizontal length between the endpoints)
Slope formula
Slope = rise/run = change y/change x= y1-y2/x1-x2
★ The rise is POSITIVE if we count UP↑, and NEGATIVE if we count Down↓
The run is POSITIVE if we count RIGHT→, and NEGATIVE if we count LEFT←
Q. Calculate the slope of (1,3) and (4,9)
A. Slope = 2
