Given :
A line 2x + 1 =0 .
To Find :
The slope of the given line .
Solution :
We know , slope of line is given by the tangent of the angle between the x-axis and the line .
Now, for line 2x + 1 =0 i.e .
The line is perpendicular to x-axis and cuts the x-axis at .
Therefore , the angle between the line and x-axis is .
So , slope i.e undefined .
Therefore , the slope of given line is not defined .
Hence , this is the required solution .
