<u>Answer-</u>
<em>A. strong negative correlation.</em>
<u>Solution-</u>
<u>Direction of a relationship</u>
- Positive- If one variable increases, the other tends to also increase. If one decreases, the other tends to also. It is represented by positive numbers(i.e 0 to 1).
-
Negative- If one variable increases, the other tends to decrease, and vice-versa. It is represented by negative numbers(i.e 0 to -1)
<u>Strength of a relationship</u>
- Perfect Relationship- When two variables are linearly related, the correlation coefficient is either 1 or -1. They are said to be perfectly linearly related, either positively or negatively.
- No relationship- When two variables have no relationship at all, their correlation is 0.
As in this case, correlation coefficient was found to be -0.91, which is negative and close to -1, so it is a strong negative correlation.

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Check all points:
A: x=0, y=10, then from the equality 
follows that A lies on the line.
B: x=3, y=13, then from the equality 
follows that B lies on the line.
C: x=8, y=2, then from the inequality 
follows that C doesn't lie on the line.
D: x=5, y=15, then from the equality 
follows that D lies on the line.
