Question

The graph of a system of parallel lines will have no solutions.

Always

Sometimes

Never

Answer 1

Always

Answer 2

sometimes

Answer 3

x+y=1

2x+2y=2

have all solutions

Answer 4

can u show me how would u solve it?

Answer 5

multiply the top by -2, combine them and get:

0=0

when does 0=0?

Answer 6

i think this is called trivial solution, it exist, but not used

Answer 7

lol, its used ...

Answer 8

granted that they are the "same" line; but its still a system of parallel lines that has at least one solution

Answer 9

Always
The example given by amistre64 is an example of coincident lines.
Line that lie on-top one-another are called coincident line, not called parallel, they intersect at every point.

Answer 10

yes, the question is about parallel, the never intersect

Answer 11

i wonder if the person who wrote the question that this came from knows that :/

Answer 12

thanx 4 the medal, but i really like to know the right answer

Answer 13

if we are to define parallel as wholly different from coincident; then the answer is never

otherwise my concept would be correct .... i would defer to the person who wrote the material from which the question was obtained :)

Answer 14

so they will "never have a solution"
OR
The graph of a system of parallel lines will have no solutions. "Always"
