(a)

1.  (i)   (ii)    Hence, point, is 1. (i) (ii)

Let be the point on (i). Then,   Hence, the required point is either (3, 1) or 2. Since lines and are perpendicular, orthocentre of the triangle is the point of intersection of these lines, i.e, 3. Since, are in A.P., so  Comparing with the line , we have and . Hence, lines are concurrent at Next Question :
 Column-I Column- II (A) If lines and are concurrent, then value of is (p) (B) If the points and are collinear, then the value of is (q) (C) If line , passing through the intersection of and , is perpendicular to one of them, then the value of is (r) 4 (D) If line is equidistant from the points and (3, 4) then is (s) 2 CODES : A B C D a) P,q q s,t r b) s,p q,r t q c) s t,s q p,q d) p,s q,s p,r s
