QUICK HELP PLEASE! How many solutions will this system of equations have? y = -3.5x - 3.5 y = -3.5x + 3.5

OpenStudy (anonymous):

No solution Infinite solutions One solution Two solutions

OpenStudy (mertsj):

Do you see that those two lines have the same slope?

OpenStudy (anonymous):

yes

OpenStudy (mertsj):

And what kind of lines have equal slopes?

OpenStudy (anonymous):

parallel?

OpenStudy (mertsj):

yes. And how many times do parallel lines intersect?

OpenStudy (anonymous):

0?

OpenStudy (mertsj):

Yes. And so how many solutions does a system of 2 parallel lines have?

OpenStudy (anonymous):

Its Zero then? No solutions?
