Dante Ferrell · Answer 1

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

Valentine · Answer 2

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
