Answer
The two lines are parallel.
Work Step by Step
RECALL:
(1) Parallel lines have equal slopes.
(2) Perpendicular lines have slopes whose product is $-1$.
(3) The slope-intercept form of a line's equation is $y=mx+b$ where $m$ = slope.
Write the second equation in slope-intercept form to obtain:
$2y-4x-5=0
\\2y = 4x+5
\\\dfrac{2y}{y}=\dfrac{4x+5}{2}
\\y=2x + 2.5$
Both lines have $m=2$ therefore they are parallel.
