A variable line passes through a fixed point P. The algebraic sum of the perpendiculars drawn from the points (2, 0), (0, 2) and (1, 1) on the line is zero. Find the coordinates of the point P \[\] [Hint: Let the slope of the line be $m$. Then the equation of the line passing through the fixed point $P (x_1 , y_1 )$ is $y - y_1 = m (x - x_1 )$. Taking the algebraic sum of perpendicular distances equal to zero, we get $ y - 1 = m (x - 1). $ Thus $(x_1 , y_1 ) $ is $(1, 1)$.]

The origin is translated to (1,2). The point $(7,5)$ in the old system undergoes the following transformations successively. (i) Moves to the new point under the given translation of origin. (ii) Translated through 2 units along the negative direction of the new X-axis. (iii) Rotated through an angle $\large\frac{\pi}{4}$ about the origin of new system in the clockwise direction. The final position of the point (7,5) is
