Question

Line A is represented by the equation given below:

x + y = 2

What is most likely the equation for line B, so that the set of equations has infinitely many solutions?

2x + 2y = 2
2x + 2y = 4
2x + y = 2
x + y = 4

Answer 1

I think this may be D

Answer 2

Do you know what the system must equal for solutions: \[\pm(x \pm y) = \infty \]

Answer 3

Why do you think so? @MilaHutcherson

Answer 4

because there are a lot of numbers you can add together to get 4

Answer 5

@Compassionate no

Answer 6

D is incorrect.

Answer 7

When they both equal the same thing, x and y = z, then that means the lines overlap

Answer 8

How do I find the answer for this?

Answer 9

Take x + y = 2
and plug it in with trial and error. When x and y both equal the same thing, then you have your answer

Answer 10

Find for x and y.

Answer 11

ok

Answer 12

What did you get?

Answer 13

hold on

Answer 14

would it be b ?

Answer 15

Yes, I believe so.

Answer 16
