no solution
one solution
infinitely many solutions

its only one right

Answer 1

2 equations 2 veriables.... trid to solve it?

Answer 2

or you don't even have to....

Answer 3

what do you mean?

Answer 4

yes so they can only intercect once right?

Answer 5

Exactly.

Answer 6

oh thanks

Answer 7

how azbout this? How many solutions exist for the system, x + y = 1 and y = -x + 1?
no solution
one solution
infinitely many solutions

Answer 8

unless y=m_1x+b and y=m_2x+b where m_1=m_2 then they are what? ;)

Answer 9

im sorry you lost me

Answer 10

\[y=1-x=-x+1\]\[x+y=1\]

Answer 11

sorry wrong order... but you see the rewriting?
