Question

Which two lines are parallel? 1) 4y=3x-4 2)4y=-1-3x 3) 4y+3x=-1

Answer 1

1 and 3 are parallel because the slopes are the same

Answer 2

according to the standard line equation

y=mx+c

on comparing the given equations with the standard one

for 1)m=3/4
2)m=-3/4
3)m=3/4
clearly line 1 and 3 have the same slope


hence 1 and 3 are parallel

hope you understand
