Question

Exercise - 6.3
Show that the lines are 3.x + 2y + 9 = 0 and 12x + 8y - 15 = 0 are parallel lines.​

Answer 1

Answer:

yes lines are parallel each other

Step-by-step explanation:

The coifficient of x is 3 and 12 , y is 2 and 8

comparing the given equation with a1x +b1y+c1 = 0 and a2x+b2y+c2=0

a1/a2 = 3/12=1/4

b1/b2 =2/8=1/4

c1/c2= 9/-15

here,

a1/a2=b1/b2 is not equal to c1/c2

therefore, lines are parallel.
