Question 181846
Find the slopes of each line
{{{y = mx + b}}}
{{{y= (-1/2)x+3}}}  so m=-1/2 

{{{8x + 16y = 32}}}
{{{16y = -8x + 32}}}
{{{y = (-1/2)x + 2}}} so m = -1/2 on this line

Both lines have the same slope ... so they are parallel lines
They have different y intercepts, so they are different lines.
