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: Answer: | | x = -3 ] ] (More)
