Learning Contents: ·          Meaning of Slope ·          Types of Slope ·          Calculating slope numerically Slope Slope measures the steepness and tells the direction of a line. It indicates the rate of change i.e. how fast y is changing with respect to x. In other words, slope is the difference between the two points in the  vertical direction  (rise) and then  divide by the difference in the horizontal  direction (run). The formula of the slope is rise over run.  Whereas, Rise indicates the movement (up or down) of a point along the y- axis i.e. Δ Y= Y 2 -Y 1        Run indicates the movement (left or right) of point long the x-axis i.e. Δ X= X 2 -X 1   Types of Slope The slope of a line is classified into four different categories that are as follows: 1.       Positive Slope 2.       Negative slope 3.       Zero Slope 4.       Undefined Slope   1.       Positive slope is a slope when the line goes uphil
