Which of the following relations is correct with respect to two parallel lines `a_(1)x+b_(1)y+c_(1)=0` and `a_(2)x+b_(2)-y+c_(2)=0` ?

A

`(a_(1))/(a_(2))=(b_(1))/(b_(2)) ne (c_(1))/(c_(2))`

B

`a_(1)b_(1)c_(1)=a_(2)b_(2)c_(2)`

C

`a_(1)b_(2) ne a_(2)b_(1)`

D

`(a_(1))/(a_(2))=(b_(1))/(b_(2))=(c_(1))/(c_(2))`

Find the condition for two lines a_(1)x+b_(1)y+c_(1)=0 and a_(2)x+b_(2)y+c_(2)=0 to be (i) parallel (ii) perpendicular

Show that the equation of the straight line through (alpha,beta) and through the point of intersection of the lines a_(1)x+b_(1)y+c_(1)=0 and a_(2)x+b_(2)y+c_(2)=0 is (a_(1)x+b_(1)y+c_(1))/(a_(1)alpha+b_(1)beta+c_(1))=(a_(2)x+b_(2)y+c_(2))/(a_(2)alpha+b_(2)beta+c_(2))

Statement - 1 : For the straight lines 3x - 4y + 5 = 0 and 5x + 12 y - 1 = 0 , the equation of the bisector of the angle which contains the origin is 16 x + 2 y + 15 = 0 and it bisects the acute angle between the given lines . statement - 2 : Let the equations of two lines be a_(1) x + b_(1) y + c_(1) = 0 and a_(2) x + b_(2) y + c_(2) = 0 where c_(1) and c_(2) are positive . Then , the bisector of the angle containing the origin is given by (a_(1) x + b_(1) y + c_(1))/(sqrt(a_(2)^(2) + b_(1)^(2))) = (a_(2) x + b_(2)y + c_(2))/(sqrt(a_(2)^(2) + b_(2)^(2))) If a_(1) a_(2) + b_(1) b_(2) gt 0 , then the above bisector bisects the obtuse angle between given lines .

Assertion (A) :Pair of linear equations 9x+3y+12=0 and 18x+6y+24=0 have infinitely many solutions Reason (R ) : Pair of linear equations a_(1)x+b_(1)y+c_(1)=0 and a_(2)x+b_(2)y+c_(2)=0 have infinitely many solutions if (a_(1))/(a_(2))=(b_(1))/(b_(2))=(c_(1))/(c_(2))

Statement -1 If system of equations 2x+3y=a and bx +4y=5 has infinite solution, the a=(15)/(4),b=(8)/(5) Statement-2 Straight lines a_(1)x+b_(1)y+c_(1)=0 and a_(2)x+b_(2)y+c_(2)==0 are parallel if a_(1)/(a_(2))=b_(1)/(b_(2))nec_(1)/c_(2)
