Are the lines below parallel, perpendicular, or neither? 7x – 4y = 4 x – 4y = 3

Paralell meas same slope
perpendicular means slopes multiply to get -1

so
in form
ax+by=c
-a/b=slope

7x-4y=4
-a/b=-7/-4=7/4

x-4y=3
-a/b=-1/-4=1/4

7/4 and 1/4
not paralell
not perpendiuclar

answer is nither

Neither (slopes would be same if parallel, slopes will be opposite reciprocals if perpendicular)

7x - 4y = 4 
-7x        -7x
-4y       = -7x + 4 
/-4               /-4 
y          = 7/4x - 1

x - 4y = 3
-x         -x
-4y     = -x + 3
/-4            /-4
y        = 1/4x -3/4 
 

The answer would be b
