Write in Short
Find the equation for the line which is perpendicular to and passing through point (6, 3).
- So, slope of two perpendicular lines is .
So, we can find slope of required line by using slope of given line which has slope
So, slope of required line =
So, now by using formula of equation passing through a point (6, 3):
, where, and m = … (from (I) ).
