    The slope of a line shows us where the line increases or decreases.
    Positive slope
    Negative Slope
    Zero slope
    When the slope is positive, it means that as we view the graph of the line from left to right, as x increases, so does y. We write m > 0
    		When the slope is negative, it means that as we view the graph of the line from left to right, as x increases y decreases . We write m < 0
    When the line has zero slope, we have a horizontal line. We write y = n, where n is a constant, and say that m = 0

    Determine whether the slope of the following lines is positive, negative o zero:

     
    Line 1


    Line 2


    Line 3

    Negative slope
    Zero slope
    Positive slope

    Negative slope
    Zero slope
    Positive slope

    Negative slope
    Zero slope
    Positive slope
