None of these
The angle between lines and is.
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 coordinates of foot of perpendicular from (x1,y1) on ax + by + c = 0 are
For which values of a and b are intercepts on axis by line ax + by + 8 = 0 equal and opposite in sign of intercepts on axis by line 2x + 3y + 6 = 0.
a = 8/3 b = -4
a = -8/3 b = -4
a = 8/3 b = 4
a = -8/3 b = 4
