Answer Key : (c) -

(c)

Reflection about the line , changes the point (4, 1) to (1, 4). On translation of (1,4) through  distance of 2 units along  direction of -axis the point becomes (1+2, 4), i.e., (3, 4)

On rotation about origin through an angle , the point  takes the position  such that . Also  and . Now,



Next Question :

Line  has intercepts  and  on the coordinates axes. When the axes are rotated through a given angle keeping the origin fixed, the same line  has intercepts  and . Then,

a)

 

b)

c)

d)
