Ski bird Task
What is slope?
Is there a different types of slope?
Positive Slope
Lines that have positive slope, slant "up hill"
Negative Slope
Lines that have negative slope, slant “down hill"
Zero Slope
Lines that are horizontal have a zero slope
No Slope or Undefined Slope
Vertical lines have no slope, or undefined slope.
Classify the slope of each of these lines as positive, negative, zero slope, or no slope…

Vertical Change (UP)Horizontal Change (OVER)
Yes, it is usually a fraction.Yes, you simplify.Yes, it can be improper.
Instructions:Draw each diagram. Measure the rise and run.Label your diagram.Find each slope.

Mount Neverest (Not drawn to scale)Measure the rise and the run of each part of the mountain in centimeters. Find the slope of each part.
How many points do you need to draw a line?
• One
• Two
• Three
Graph (3,2) and (-1,-1)
Draw a line through the points
Now that we have our line let’s find its slope…
Remember we are finding the following ratio:
Vertical Change or Rise Horizontal Change Run
Vertical Changeor the Rise

Horizontal Changeor the Run

Find the slope of these lines.
The slope is…
• Black line 3
• Red Line 1
• Blue Line -1/2
Find the slope of these lines
The slope is…
• Orange line 0
