Slope is the steepness of a line.Slope is seen everywhere!

Slide3

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

Slide4

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

There is less snow build up in the wintertime.

Slide7

Slopes and Lines

rise

run

The slope of a line is the rise divided by the run. It is often left

as a fraction

.

Slide8

A grade of 8% would mean that for every run of 100 units, there is a rise of 8 units.
