What is slope?
Is there a different types of slope?
![Page 3: Ski bird Task What is slope? Is there a different types of slope?](https://reader036.fdocuments.net/reader036/viewer/2022062716/56649dbf5503460f94ab3ebb/html5/thumbnails/3.jpg)
Positive Slope
Lines that have positive slope, slant "up hill"
![Page 4: Ski bird Task What is slope? Is there a different types of slope?](https://reader036.fdocuments.net/reader036/viewer/2022062716/56649dbf5503460f94ab3ebb/html5/thumbnails/4.jpg)
Negative Slope
Lines that have negative slope, slant “down hill"
![Page 5: Ski bird Task What is slope? Is there a different types of slope?](https://reader036.fdocuments.net/reader036/viewer/2022062716/56649dbf5503460f94ab3ebb/html5/thumbnails/5.jpg)
Zero Slope
Lines that are horizontal have a zero slope

No Slope or Undefined Slope
Vertical lines have no slope, or undefined slope.

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
