SLOPE OF A LINE #1--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   4   Slope 1/2 = 0.5  	  2) Rise   4   Run   2   Slope 4/2 = 2           3) Rise   6   Run   1   Slope 6/1 =  6                    

	

4) Rise   4   Run   3   Slope 4/3 = 1.3  	  5) Rise   4   Run   8   Slope 1/2 = 0.5        6) Rise   12   Run   4   Slope 12/4 = 3                  

7) Rise   6   Run   6   Slope 6/6 = 1  	  8) Rise   2   Run   10   Slope 2/10 = 0.2        9) Rise   12  Run   12  Slope 12/12 = 1
