Question

Graphically ,the pair of equation 6x-3y+10=0;2x-y+9=0 represent two lines which are

Answer 1

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.

Option D is correct.

Hope it helps.
