The equation y = - 4 in two variables x and y, can be written as
  • A
    $1 \cdot x+1 \cdot y=-4$
  • B
    $1 \cdot x+0 y=-4$
  • C
    $0 x+1 \cdot y+4=0$
  • D
    $0 x+1 \cdot y=4$
✓

Answer

C. $0 x+1 \cdot y+4=0$
Equation $y=-4$ can also be written as $0 \cdot x+1 \cdot y=-4$ or, $0 \cdot x+1 \cdot y+4=0$.
