Given information :
Two lines are tangent to the
Formula used:
The slope of
Explanation :
Consider the figure.
From the figure the slope of the tangent line at
The slope of the tangent line at
From the above two slopes, it is clear that one tangent’s slope is negative reciprocal of another tangent’s slope.
