SLOPE OF A LINE #2--KEY

Directions: The slope of a line measures the steepness of a graph.  To calculate the slope, you must find the quotient of the rise and run of the line.  The rise measures the vertical change, or change in y-coordinates, between the two points.  The run measures the horizontal change, or change in x-coordinates, between the two points.  Find the slope of each line below.  You can express the slope as a simplified fraction, a whole number, or a decimal.

1) Rise 2   Run   5   Slope 2/5 = 0.4  	  2) Rise -5  Run   5    Slope -5/5= -1      3) Rise  5     Run  10   Slope 1/2 = 0.5                                                          

	

	

4) Rise_8_  Run   2    Slope 8/2 = 4   	  5) Rise -3  Run   10  Slope -3/10 = -0.3   6) Rise   1    Run  10   Slope 1/10 = 0.1                  

7) Rise_-4  Run   3   Slope -4/3 = -1.3   8) Rise_10  Run   8    Slope 10/8 = 1.2    9) Rise -14  Run  10  Slope -14/10 = -1.4
