You can put this solution on YOUR website!
check the slopes; parallel lines have same slope
A.
y-2x=+-5 and 2x-y=+-6 in slope-intercept form
y=+highlight%282%29x-5 and y=highlight%282%29x%2B6 ...same slope; so, these two lines are parallel to each other
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+2x-5%2C+2x%2B6%29+
we will check these too,
B.
2x%2By=+-5 and 2x-y=+-6
y=highlight%28-2%29x-5 and y=highlight%282%29x%2B6... slopes are not same;-2%3C%3E2...these two lines are NOT parallel to each other

+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+-2x-5%2C+2x%2B6%29+
C.
y-2x+=+-5 and 2x-y+=+6
y+=+highlight%282%29x-5 and y=highlight%282%29x-6...same slope; so, these two lines are parallel to each other
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+2x-5%2C+2x-6%29+

D.
-2x%2By=+-5 and 2x%2By+=+6
y=highlight%282%29x+-5 and y+=highlight%28-2%29x%2B+6}}}... slopes are not same;-2%3C%3E2...these two lines are NOT parallel to each other
