To determine the slope, subtract the y coordinates from each other and the x coordinates as well. That gives us: 10000 - 4000 over 0 - 15, which simplifies to 6000 over -15. When divided, it results in -400. So, the slope amounts to -400. I hope this aids you!:D
Response:
The number 40 can be found in Pattern B. Additionally, following the rule, each sequence will expand.
Detailed breakdown:
Let’s build each sequence. Recall that the guideline is to "add 15" to generate each sequence starting from the provided initial number.
Pattern A.

Pattern B.

Pattern C.

You can see that the number 40 appears in Pattern B. Moreover, per the rule, each pattern will show an increase.
Answer:
The answer is the scatter plot that displays a pronounced positive slope along the curve of best fit.
Step-by-step explanation:
A scatter plot illustrates the relationships between two variables for an individual. It is essentially a graph in which a best-fit curve is drawn to encapsulate the complete dataset. A scatter plot is considered to have a robust correlation if the correlation coefficient is near r = 1, indicating a very strong connection between the two variables.
A scatter plot exhibits a solid correlation when its data points are closely aligned to the line or curve of best fit.
For r = 1, the correlation is regarded as strong and positive.
