SLOPE OF A LINE #5--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 -8  Run   2   Slope  -8/2 = -4   	  2) Rise_0_ Run   8  Slope      0             3) Rise   1   Run  5   Slope   1/5 = 0.2_
