2x-y+9=0
Represents two line which are
(A) intersecting at exactly one point
(B) intersecting at exactly two point
(C) coincident
(D) parallel
​

Answer 1

Step-by-step explanation:

Correct option is

Correct option isD

Parallel

The linear equations are

The linear equations are6x−3y+10=0

The linear equations are6x−3y+10=02x−y+9=0

The linear equations are6x−3y+10=02x−y+9=0Here, a1=6,b1=−3,c1=10

The linear equations are6x−3y+10=02x−y+9=0Here, a1=6,b1=−3,c1=10a2=2,b2=−1,c2=9

The linear equations are6x−3y+10=02x−y+9=0Here, a1=6,b1=−3,c1=10a2=2,b2=−1,c2=9∴a2a1=26=3

The linear equations are6x−3y+10=02x−y+9=0Here, a1=6,b1=−3,c1=10a2=2,b2=−1,c2=9∴a2a1=26=3b2b1=−1−3=3

The linear equations are6x−3y+10=02x−y+9=0Here, a1=6,b1=−3,c1=10a2=2,b2=−1,c2=9∴a2a1=26=3b2b1=−1−3=3c2c1=910

The linear equations are6x−3y+10=02x−y+9=0Here, a1=6,b1=−3,c1=10a2=2,b2=−1,c2=9∴a2a1=26=3b2b1=−1−3=3c2c1=910⇒a2a1=b2b2=<

Answer 2

Answer:

D parallel

Step-by-step explanation:

6x-3y+10=0

2x-y+9=0

6/2=3/1=10/9

3/1= 3/1 =10/9

first lines are eual but third line is not equal to first two lines

so It is parallwl
