What is slope?

Are there 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…

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:
