The graphs of $2x + y = 3,\; 4x + 2y = 6$ are —

acoincident
bparallel
cintersecting
dperpendicular

ব্যাখ্যা

The second equation $4x + 2y = 6$ is exactly twice the first, $2x + y = 3$ , so they represent the same straight line. Identical equations produce coincident graphs with infinitely many common points.
