step-by-step explanation:

worked it out i believe

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

b=-6

compare the slopes

m

m of the two equations.

,

m

2

=

0

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
