Question

Consider the following pair of equations:

−x − y = −5
y = x + 1

If the two equations are graphed, at what point do the lines representing the two equations intersect?

(−2, 3)
(3, −2)
(2, 3)
(3, 2)

Answer 1

WHAT DO U THINK

Answer 2

b

Answer 3

\[-x-(x=1)=-5\]

Answer 4

I have no idea

Answer 5

distribute the negative 1st

Answer 6

\[-(x+1)\]

Answer 7

- + -1

Answer 8

-x-1

Answer 9

-x + -1 **

Answer 10

\[-x-x-1=-5\]

Answer 11

-x -1 = -5

Answer 12

whats -x-x?

Answer 13

idk D:

Answer 14

ok you are technically subtracting from -1 therefore you get -2 now you have
\[-2x-1=-5\]

Answer 15

do you know what to do next?

Answer 16

-5+-1?

Answer 17

no never put +-1 it makes no sense but you have the right idea what is -5+1?

Answer 18

-4

Answer 19

good! now what is :
\[-2x/-4\]

Answer 20

2

Answer 21

x = 2

Answer 22

yep i think you can determine what your answer will be from that :)

Answer 23
