Hi,

 Lines:  

 x + 2y=6           0r    y = -x/2 + 3
2x = -4y + 10       0r    y = -x/2 + 10/4
y = (-1/2)x + 5     0r    y =  (-1/2)x + 5 

  Lines are parallel:  might find them
{{{drawing(300,300,   -6, 6, -6, 6, grid(1), 

graph( 300, 300, -6, 6, -6, 6,0, -x/2 + 3, -x/2 + 10/4, (-1/2)x + 5   )) }}}

Wish You the Best in your Studies.
