Question

Show graphically the given system of equations 2x + 3y = 9 and 4x + 6y = 18 has infinite many
solutions/ coincident lines.

Answer 1

Step-by-step explanation:

Comparing equation 2x+3y=9 with a1x + b1y+c1 =0 and 4x+6y=18 with a2x+b2y+c2=0

we get a1=2, b1=3, c= -9

a2=4, b2=6. c= -18

HERE. a1/a2 = b1/b2 =c1/c2

Therefore by thus we conclude that

these linear equation has a coincident pair of lines and has infinite number of possible outcome
