The slope of any line perpendicular to given line is (-1/6)

Explanation:

We know that,

(1) Slope of the line passing through A(x_1,y_1)and B(x_2,y_2) is

m=(y_2-y_1)/(x_2-x_1)

(2) If the slope of the line l_1 is m_1and the slope of
the line
l_2 is m_2 then

l_1_|_l_2 <=>m_1m_2=-1

We have line l_1 passing through A(-4,1)andB(-3,7).

Using (1) we get

m_1=(7-1)/(-3+4)=6

Now from (2),we have

m_1m_2=-1

=>(6)m_2=-1

=>m_2=-1/6
