Answer:
The slope of the line through the points (-2,-1) and (8,-3) is -0.2. Have a nice day and hope this helps.
Answer:To calculate the standard deviation of those numbers:
1.Work out the Mean (the simple average of the numbers)
2.Then for each number: subtract the Mean and square the result.
3.Then work out the mean of those squared differences.
4.Take the square root of that and we are done!
Step-by-step explanation:
1. 8
2. 25
3.40
plug in the expressions
I do believe it would be a 2.2
