Question

On comparing the ratios a1a2, b1b2 and c1c2 , find out whether the pair equations 2x-6y+10=0 and 3x-9y+15=0 are intersecting, coincident or parallel.

Answer 1

Answer:

Let a1= 2 b1 = -6 c1 = 10

a2 = 3 b2 = - 9 c2 = 15

Step-by-step explanation:

Now,

comparing

a1/a2 = 2/3

b1/b2 = -6/-9 = 2/3

c1/c2 = 10/15 = 2/3

Hence it is coincident.
