Question

if A1/A2=b1/b2=C1/C2 then the lines are _lines

​

Answer 1

Step-by-step explanation:

the 2 linear equations

a1x+b1y+c1=0

a2x+b2y+c2 =0

have infinite solutions when

a1/2 = b1/b2 = c1/c2

and they represent the same line

Answer 2

Answer:

If both the lines intersect at a point, then there exists a unique solution to the pair of linear equations. ... If a1 / a2 = b1 / b2 = c1 / c2 , then the pair of lines are coincident and the pair of equations is dependent and consistent.
