Question

2. Are the lines 2x - y = 2, 4x - y = 8 parallel?​

Answer 1

Step-by-step explanation:

Given :-

the lines 2x - y = 2, 4x - y = 8

To find:-

Given lines are parallel or not

Solution :-

Given pair of linear equations in two variables

are 2x-y=2=>2x-y-2=0

a1=2;b1=-1;c1=-2

and,

4x-y=8=>4x-y-8=0

a2=4 ; b2=-1;c2=-8

a1/a2=2/4=1/2

b1/b2=-1/-1=1

C1/c2=-2/-8=1/4

a1/a2≠b1/b2≠c1/c2

So given lines are not parallel lines

Answer:-

Given lines are not parallel lines.

They are Intersecting lines.

Used concept:-

If a1/a2≠b1/b2 then the lines are consistent they are called intersecting lines with only one solution.
