The regression line equation is

, the value of the slope is shown as constant 16 and it's a positive constant, hence the correlation between the amount of gas used and degree of the days is a POSITIVE correlation.
Now it would be
-2.3+(-5.9)
now just add those two together
and u get -8.2
So the answer is A

Answer:
(Negative two-fifths) (Negative StartFraction 8 over 9 EndFraction) (one-third) (StartFraction 2 over 7 EndFraction)
Step-by-step explanation:
(Negative two-fifths) (Negative StartFraction 8 over 9 EndFraction) (one-third) (StartFraction 2 over 7 EndFraction) = (-2/5)(-8/9)(1/3)(2/7)
Let's take the fraction and eliminate the negative sign because negative multiply negative= positive
(-2/5)(-8/9)(1/3)(2/7)= 32/945
