A.


(1, –10)


B.


(2, –8)


C.
(1, 2)


D.
(2, 8)

Answer 1

6x + y = –4

plug in choice A. It works !

6(1) + (-10) = –4
6 - 10) = –4
-4 = –4

Answer 2

So it's A?

Answer 3

Just like student_basil said. You never know which one works correctly. I will work out B for you and let you see. Just plug it in.
6x+y=-4
6(2) +(-8) = -4
12 + -8=-4
\[4\neq -4\]

Answer 4

??

Answer 5

And yes! Choice A is correct!

Answer 6

A carpenter charges a one-time fee of $50 plus $35 for each hour on the job. If n is the number of hours on the job and c is the total charge for the work done, then the variables are related by the equation c = 35n + 50.



Which variable is the independent variable?

n


B.


c


C.
