The foot of perpendicular drawn from origin to the line joining points (a cos a, a sin a) and (a cos β , a sin β) is
None of these
If lines 3x - y =2,5x + ay = 3 and 2x + y = 3 are concurrent ,then a =

A line moves in such a way that the sum of reciprocals of intersection on two mutually perpendicular lines by the line remains constant than the line passes through
Fixed Point
A variable point
Origin
The coordinates of foot of perpendicular from origin to the line 3x+4y -5 = 0 is
The lines ax + by + c + = 0 , bx + cy + a = 0 and cx + ay + b = 0 are concurrent, if
a3 + b3 + c3 + 3 abc = 0
a3 + b3 + c3 - 3 abc = 0
a3 - b3 + c3 - 3 abc = 0
The equation of line passing through (c , d) and parallel to ax + by + c = 0 is
a (x +c ) + b ( y + d) = 0
a (x + c) - b (y + d) = 0
a (x - c) + b (y + d) = 0
a (x - c) - b (y - d) = 0
The gradient of line which cuts equal intercepts with coordinate axis is.
