Maximum and minimum value of correlation coefficient are 1 and -1 respectively.
When coefficient (r) = 1, it means that every data set values lies on a straight line or you can say that there is perfect positive linear relationship between two variables. When coefficient(r) = -1, it means that every data set values lies on a straight line but this straight line has negative slope. So they are also said to be perfect negative linearly related.
Answer:
y = 3+1/2
that should be the answer
X = 6 is vertical, so it has infinite slope
Answer: 
Step-by-step explanation:
1. Based on the information given in the problem, you can draw the right triangle shown in the figure attached.
2. Keeping the informationn given in the problem, you can calculate the angle that the sum makes with the ground (
)as you can see below:
Where:
3. Then:
