Example 1:<br />
Charlene is working on a project in her Art Metal<br />
class. She wants to make a brass cookbook holder<br />
like the one in the diagram. She does not have a<br />
protractor to measure the angle, but the diagram<br />
is drawn on graph paper.<br />
What is the slope <strong>of</strong> the cookbook holder<br />
a) as a simplified fraction b) as a decimal<br />
Solution:<br />
Example 2:<br />
Duncan <strong>and</strong> Casey are using h<strong>and</strong> trucks to move small boxes from a<br />
house to a garage. They lay a loading ramp against the house steps<br />
which are 18’’ high. The slope <strong>of</strong> the steps is 0.2.<br />
What is the horizontal distance in feet from the base <strong>of</strong> the ramp to<br />
the point x .<br />
