Question

Graphically, the pair of equations

6x – 3y + 10 = 0

2x – y + 9 = 0

Represents two lines which are:

​

Answer 1

PARALLEL, NO SOLLUTION

Compare the equations with:

6x-3y+10=0

2x-y+9=0

We get

a1 = 6

a2=2

b1=-3

b2=-1

c1=10

c2=9

a1/a2=6/2

=3

b1/b2=-3/-1

=3

c1/c2

=10/9

a1/a2=b1/b2≠c1/c2

So the equation has no solution

Hence the lines are parallel.

Hope it helps.

Answer 2

Answer: $parallel$

Explanation:

Here

a1/a2=6/2=3/1

=> b1/b2= -3/-1=3/1

c1/c2=10/9

This implies,

a1/a2=b1/b2≠c1/c2

Therefore, lines are parallel.
