Question

Line A is represented by the equation given below:

x + y = 4

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

Answer 1

i need help!

Answer 2

multiply line A by any number except 0 and it will still be the equation of the same line. You could multiply by 2 and get 2x + 2y = 8 or multiply by -5 and get -5x - 5y = - 20.

Answer 3

4x + 4y = 4
4x + y = 4
2x + 2y = 8
x + y = 8

Answer 4

so would it be D?

Answer 5

i ment C

Answer 6

yes

Answer 7

thank you
