Answer:
Lines are parallel.
Step-by-step explanation:
The given lines are
Rearrange the equation in the slope intercept form that is where
is the slope.
<em>First Line:</em>
compare it with
slope () of first line
<em>Second Line:</em>
divide both by
compare it with
slope of second line
Since slope of two lines are equal
hence these lines are parallel.
