Rate of Change of a Linear Relationship

The rate of change of a linear relationship is the steepnessof the line.


Rates of change are seen everywhere
Rates of change are seen everywhere.


The steepness of the roof of a house is referred to as the pitch of the roof by home builders.


Give one reason why some homes have roofs which have a greater pitch.

There is less snow buildup in the wintertime.

Rate of change =

A grade of 8% would mean for every rise of 8 unitsthere is arun of 100 units.

= 8%
