Answer: x = (-3,3), y = (-5,5)
Step-by-step explanation:
Add both of the equations together, for 
. Now we can divide both sides by 3, getting
. we subtract the first equation from our equation we just got, getting 
y= (5,-5). once we plug that in, we get 
, 
x = (-3,3)

Answer:
Step-by-step explanation:
Substituting y = 4x+1 into 2y = -x-1 gives the equation
2(4x+1) = -x-1
Solve the equation:
8x+2 = -x-1
9x = -3
x = -⅓
Answer:
C
Step-by-step explanation:
The correlation is becoming stronger, with a negative direction.
The closer a number is to the zero in the number line when its negative the more value it has.
Now if the number is negative and its away from zero in the number line the less value it has.
