Which of the following equations could be the trend line of variables that have a negative correlation?
y = -2x + 1
y =x + 1
y = 2x - 1

Weegy: -2x - 2 + 7(x + 1) = 2x - 4 is equal to x = -3
Solution:
Solve for x:
7 (x+1)-2 x-2 = 2 x-4
Distribute 7 over x+1.
7 (x+1) = 7 x+7:
7 x+7-2 x-2 = 2 x-4
Group like terms in 7 x-2 x-2+7.
Grouping like terms, [ [ 7 x-2 x-2+7 = (7 x-2 x)+(7-2):
(7 x-2 x)+(7-2) = 2 x-4
Combine like terms in 7 x-2 x.
7 x-2 x = 5 x:
5 x+(7-2) = 2 x-4
Evaluate 7-2.
7-2 = 5:
5 x+5 = 2 x-4
Move terms with x to the left hand side.
Subtract 2 x from both sides:
(5 x-2 x)+5 = (2 x-2 x)-4
Combine like terms in 5 x-2 x.
5 x-2 x = 3 x:
3 x+5 = (2 x-2 x)-4
Look for two terms that sum to zero.
2 x-2 x = 0:
3 x+5 = -4
Isolate terms with x to the left hand side.
Subtract 5 from both sides:
3 x+(5-5) = -4-5
Look for two terms that sum to zero.
5-5 = 0:
3 x = -4-5
Evaluate -4-5.
-4-5 = -9:
3 x = -9
Solve for x.
Divide both sides of 3 x = -9 by 3:
(3 x)/3 = (-9)/3
Any nonzero number divided by itself is one.
3/3 = 1:
x = (-9)/3
Reduce (-9)/3 to lowest terms.
The gcd of -9 and 3 is 3, so (-9)/3 = (3 (-3))/(3?1) = 3/3?-3 = -3:

| x = -3
