    The slope of the line shown in the given figure

    A)  2                                            

    B)  1

    C)  -1                          

    D)         - 2  

    Correct Answer: D

    Solution :

     Here, as we can see from the figure that the line passes through points \[(-1,0)\] and \[(0,-2)\] when it crosses x-axis and y-axis. The slope of a line is given by the ratio of the changes in y-value to the change in x- value.                 \[\therefore \] Slope of the line, \[m=\frac{(-2)-(0)}{0-(-1)}=-\frac{2}{1}=-2\]
