Help lol, show wurk cuz u know how teachers are these days
telo118 [61]

Answer:

Infinitely many solutions (the lines are identical)

Step-by-step explanation:

Let's start by getting each equation into slope intercept form (y=mx+b)

-14x-14y=28

-14x-28=14y

-x-2=y

and

7x+7y= -14

7x+14= -7y

-x-2=y

We can see that these two lines are identical which means that there are an infinite amount of answers
