Answer:
The slope is 2.
Step-by-step explanation:
If you use the formula that is shown in the picture, you can calculate that 12-4/6-2 is the slope. If you simplify, you'll get that 8/4 is the slope which simplifies to 2.
There is no pattern(must be a mistake?)
Answer: -0.83
Step-by-step explanation:
A correlation coefficient(r) is used to determine the strength and direction of the relationship between two variables.
-1 ≤ r ≤1
For downward trend r is negative.
For strong correlation r should be closer to 1 or -1.
From the given correlation coefficients -0.83 is both negative and closer to -1.
Hence, a correlation coefficient represents the strongest downward trend in a data set = -0.83
