Terms to Remember Universal Design: the design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design Accessibility: degree to which a product, device, service, or environment is available to as many people as possible

3
Components of a Wheelchair Ramp Horizontal Run Ramp Length Surface of Ramp Deck Length Vertical Rise Ramp Height θ

4
Slope: The slope of a line is the ratio of the change in y-coordinates to the change in x-coordinates Rate of change Vertical Change Horizontal Change

5
Slope Formula The slope m of the line passing through (x₁, y₁) and (x₂,y₂) is given by

6
Positive Slope Zero Slope Negative Slope Undefined Slope

7
Example 1: Find the slope of the line that passes through (1,3) and (-2,-3). Then graph the line. Let (x₁, y₁)=(1,3) and let (x₂, y₂)=(-2,-3)

8
Example 2: Graph the line passing through (1,-3) with a slope of 1.Plot (1,-3) 2.Use the slope to find another point 3.Then graph the line

9
Americans with Disabilities Act (ADA) Title III of the ADA prohibits discrimination on the basis of disability in “places of public accommodation and commercial facilities.” Title III outlines minimum standards for ensuring accessibility when designing and constructing a new facility or altering an existing facility. For wheelchair ramps: – The least possible slope shall be used. The maximum slope of a ramp in new construction shall be 1:12. – The maximum rise for any run shall be 30 inches.
