SLOPE OF A LINE #4--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_-9_Run   3    Slope  -9/3= -3    	  2) Rise -5_Run   5   Slope   -5/5= -1        3) Rise -5   Run  4   Slope  -5/4= -1.2                                                          

	

	

4) Rise_3_Run   9   Slope   3/9=0.3    	  5) Rise -4_Run   12  Slope -4/12= -0.3    6) Rise  10  Run   3  Slope  10/3=3.3                  

7) Rise_-4_Run   4   Slope  -4/4 = -1   	  8) Rise_10_Run   7   Slope 10/7 = 1.4      9) Rise  4   Run  5   Slope 4/5 = 0.8
