Question

IfIf a1a2=b1b2=c1c2, the system of equations are consistent , coincident lines and have infinite solutions. for the system of equations $a_{1}x+b_{1}y+c_1=0$ and $a_{2}x+b_{2}y+c_2=0$ ,then :

• A. These represent coincident lines
• B. The system of equations have infinite solutions
• C. only (a) and (b)
• D. none of these

Answer 1

The correct option is C

only (a) and (b)

If a1a2=b1b2=c1c2, the system of equations are consistent , coincident lines and have infinite solutions. the system of equations are consistent , coincident lines and have infinite solutions.
