NEW INFORMATION

Slope is the STEEPNESS of a line.

It helps us make predictions and understand proportional relationships.

Finding the Slope of a Line

Slope can tell us how steep a line is!
Slope is written as a ratio (rise/run)
Always make sure to simplify your answer!

One way to calculate a number value for slope is to count the rise (vertical change) and run (horizontal change) between any two points on the line

Rise over run

rise

run

rise

run

Multiple Choice
