Question

2x-y=2
2x-y=-2
I am thinking this is no solution or infinite solutions not sure

Answer 1

do they have the same slope?

Answer 2

2x-y=2
2x=2+y
x=2+y/2
2(2+2y/2)-y=-2

Answer 3

let me know if you need help finishing it

Answer 4

do they have the same slope? (yes)
and are they the same line? (no)
therefor....

Answer 5

Pretty much what I did was solved for x and substituted it into the second equation

Answer 6

if they are the same line, there are an infinite number of solutions
if they are parallel lines, there is no solution

Answer 7

alright thats more the definition i needed thanks to Nismo45OZ and Philips13

Answer 8

lines actually look parallel no there's no solution

Answer 9

anytime
