Slope Using Graph

Slope Using Graph

Learning Target

• I can use a graph to determine the slope of the line.

Multiple Choice

Find the slope of a line that uses the points (-2, 0) and (0, 4).

• 4

• 2

• 0

• -2

Multiple Choice

Find the slope of the line that uses the points (4, 9) and (8, 13).

• 
  

  $1$
  

• $-1$

• $4$

• $-4$

Determining Slope

•  $m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}$  

•  $m=\frac{y}{x}=\frac{rise}{run}$  

Determining Slope

• When moving down or to the left, the value will be negative.

• When moving up or to the right, the value will be positive. 

• Moved down 3 units = -3

• Moved right 4 units = 4

•  $m=-\frac{3}{4}$  

Determining Slope

• Determine the change in y.

• Determine the change in x.

• Find your slope.

4 Types of Slope
