It seems appropriate to use the linear regression function of your calculator for this. Looking at the data, you know the slope is generally positive, so only the 1st and 3rd choices are potentially viable.
A calculator shows the correlation coefficient (r) rounds to 0.816, so the appropriate selection is ...
A. 0.816
Answer:
x<-4
Step-by-step explanation:

Answer:
x +2y = 36
2x+3y =64
Step-by-step explanation:
x = price of a T-shirt
y = price of a puck
Adam buys a T-shirt and two souvenir pucks for $36.00
x +2y = 36
Luke spends $64.00 on two T-shirts and three pucks
64 = 2x+3y
Our system of equations is
x +2y = 36
2x+3y =64
