Question

On comparing the ratios,a1/a2, b1/b2, c1/C2, 5x-4y+8=0, 7x+6y=0​

Answer 1

Answer:

5/7not=4/8not =infinfty

Answer 2

Answer:

5x – 4y + 8         = 0

7x + 6y – 9         = 0

Compare the equation with

We get  

a1 = 5,            b1       = -4,               and c1 = 8

a2 =7               b2       =6                    and c2 = -9  

Hence  

So both are Intersecting lines at one point

(ii)9x + 3y + 12            = 0

18x + 6y + 24           = 0

Compare the equation with

We get  

a1 = 9,           b1       = 3,                 and c1 = 12

a2 =18          b2        =6,                   and c2 = 24  

Hence  

So both lines are coincident
