TrashWheel & Slope

TrashWheel & Slope

Learning Target

• I can identify the difference between independent and dependent variables. (MGSE8.F.1)

• I can complete data tables using the slope. (MGSE8.EE.5)

Y, the Y-Variable??

Independent vs Dependent Variable

• Independent Variable is the X-Variable

• Can be related to the "cause"

• Dependent Variable is the Y-Variable

• Can be related to the "effect"

•  $m=\frac{y-variable}{x-variable}$  

A Long Walk to Water

• Water loss occurred over long distance.

• The amount of water depended on the distance traveled.

• Distance (x, the independent variable)

• Water (y, the dependent variable)

Hotdog Mummification

• The size of the hotdog was effected over time.

• Time (x, independent variable)

• Size (y, the dependent variable)

TrashWheel

• The amount of pollution collected is determined by how long its in operation.

• The longer trashwheel operates, the more trash collected.

• Time is independent

• Trash collected is dependent

Completing Data Tables Using Slope

Mr. TrashWheel

• Cleans about 16 tons per month

• 
  
   $m=\frac{16\ tons}{1\ month}$  
  

Prof. TrashWheel

• Cleans about 4 tons per month

• 
  
   $m=\frac{4\ tons}{1\ month}$  
  

Capt. TrashWheel

• Cleans about 3.7 tons per month

• 
  
   $m=\frac{3.7\ tons}{1\ month}$
