C-12-Q082mediumsingle_mcq

The graphs of $2x - y = 4,\; 4x - 2y = 12$ are —

acoincident
bparallel
cintersecting
dperpendicular

ব্যাখ্যা

Dividing $4x - 2y = 12$ by $2$ gives $2x - y = 6$ , which contradicts $2x - y = 4$ . Equal left sides but different constants means the lines have the same slope yet never meet, so they are parallel.
