The slope is a rate of change. It can also tell us something about its angle from the horizontal.

A positive slope means an upward angle. A negative slope goes downward.

Let's take an example of a roof with a slope of 4:12. Here we mean that it rises 4 inches for every 12 inches of run.

So if we were to plot this, it would be y=(1/3)x where the slope is 4/12 or 1/3.

A slope of 1 would be something that rises one unit for every unit of horizontal run.

A positive slope means an upward angle. A negative slope goes downward.
