If a1x+b1y+c1=0, a2x+b2y+c2=0 are two equations with no solutions , then a1a2=b1b2≠c1c2
True
False
a1x+b1y+c1=0, a2x+b2y+c2=0 are two equations with no solutions(inconsistent),then
a1a2=b1b2≠c1c2
If a1x+b1y+c1=0, a2x+b2y+c2=0 are two equations with an unique solution, then a1a2=b1b2=c1c2
Parallel lines are obtained for the pair of equations a1x+b1y+c1=0 and a2x+b2y+c2=0 if
Unique point is obtained for the pair of equations a1x + b1y + c1 = 0 and a2x +b2y + c2 = 0 if __________ .
The condition for a pair of equations a1x+b1y+c1=0 and a2x+b2y+c2=0 to be parallel is
