Find the the y-intercept of the line passing through A(2,3)=(h,k) which is perpendicular to the line through the points P(6,7)=(x1,y1) and Q(6,18)=(x2,y2).
slope of PQ = (y2-y1)/(x2-x1)=(18-7)/(7-6)=11
hence slope of its perpendicular = -1/11
eqn.of line through A is
y-k=m(x-h)
y-3=(-1/11)(x-2)= (-x/11) +(2/11)
y intercept is when x=0...we get
y-3 = 2/11
y=3+2/11=35/11
