Question

Which is a solution to the equation 4x + y = –6?

A.
(–2, –2)

B.
(2, –2)

C.
(–2, 2)

D.
(2, –4)

Answer 1

What do you think is the solution?

Answer 2

To find the solution, just put each point into the equation and if equals -6 then you know it is a solution. I will do the first one.

A (-2, -2)
4x + y = –6
4(-2) + (-2) = –6
-8 + -2 = -6
-10 = - 6


-10 does not = -6 so the point A is not a solution. Do the next one, which is B.

Answer 3

Lets do B (2, -2)
B (2, -2)

4x + y = –6
4(2) + (-2) = –6
8 + -2 = -6
6 = - 6

6 does not = -6 so B is not a solution

Answer 4

Argh my reply deleted itself right after I just finished it plus I was trying to figure out how to do it sorry I took so long. My answer seemed wrong anyway I came up with 14 as an answer...but thank you for guiding me through B.

Answer 5

It's C because 4(-2)+2=-6
-8+2=-6
-6=-6

Answer 6

Correct!!!!!! Good Job
