Answer:
18
Step-by-step explanation:
In the linear regression equation y=a+bx, slope coefficient b represents average unit increases in y variable due to unit increase in x variable.
In the given equation ŷ = 84 + 18x, b=18 represents average unit increases in gas used due to unit increase in degree day.
Hence,on average, gas used increase by 18 for each additional degree-day.
Answer:
maybe number 2
Step-by-step explanation:
because if 2+k=18 then there is no other k there and where did the additional 2 come from ?and 2k=18 then value of k is 9 + there is balance.I may be wrong correct me but i think it is no.2

Answer:
Step-by-step explanation:
If two lines are parallel, their slopes (gradients) will be the same.
Ensure both line equations are in the format y = mx + b (where m is the slope and b is the y-intercept):
Line L1: y = 2x + 5
Line L2: 2y - 4x = 6
⇒ 2y = 4x + 6
⇒ y = 2x + 3
As the slopes of L1 and L2 are both 2 and therefore the same, this proves that the two lines are parallel.
