11-8 Slope quiz follow-up

We will continue to review the slope concepts.  We need to practice drawing and reading graphs on the coordinate plane (grid paper).

We need to be able to interpret graphs for vertical change and horizontal change. 
We need to be able to calculate slope by moving from point A to point B and by counting grid squares.

A horizontal line has a slope of zero.  A slope can be positive (uphill) or negative (downhill)
Slopes are a measure of steepness.  A wheelchair ramp with a large slope makes it hard to push the chair up. A wheelchair ramp with a shallow slopemay not get you high enough, or it may require a longer or more expensive ramp.
