Question

Are the straight lines x – 3y = 7 and 2x – 6y -
16 = 0, parallel ?
Ans. : Parallel
​

Answer 1

Answer:

because coefficient of x and y in equation 1 when divided by coefficient of. x and y in equation 2 then we got equal value

Answer 2

heya mate...

x-3y =7 ------1)

2x-6y=16

divided by 2 both sides,

x-3y=8 -------2)

from both equations,, we conclude that cofficient of x and y in both equations are equal...... there are different constants..

so we said that these equations are parallel...

because it is the parallel condition

• if the cofficients of x and y in two equations, are equal and there are only different between in their constants then these lines should be parallel...

hope it helps you buddy... ☺☺☺
