If the coordinates of points be and respectively and be the middle point of , then the equation of the perpendicular drawn from to the line is:
Explanation for the correct option.
Step 1: Find the slope of line
Given that is the mid-point of :
The slope of line joining is given by
Let the slope of be
Let the slope of the required line be .
The required line is perpendicular to .
Therefore,
Step 2: Find the equation of the line
This line passes through is .
Therefore, the required line is .
Hence, option C is correct.
