Question

9x + 3y + 12 = 0 and 18x + 6y + 24 = 0. represent graphically.​

Answer 1

Answer:

we have

9x+3y+12=0

18x+6y+24=0

Step-by-step explanation:

here

a¹ = 9 , b¹ = 3 ,c¹ = 12 and a² = 18 , b² = 6 , c² = 24

a¹ / a² = 9 / 18 = 1/2 ; b¹ / b² = 3/6 = 1/2 ; c¹ / c² = 12/24 = 1/2

a¹/a² = b¹/b² = c¹/ c²

so equations 1 and 2 represent coincident lines.

Answer 2

Answer:

The lines representing the pair of equations 9x + 3y + 12 = 0 and 18x + 6y + 24 = 0

a)are coincident

b)are parallel

c)intersect at a point

d)none of these
