What is the slope of the line on the graph?

C

Step-by-step explanation:

To find the slope of the line, we need to use the formula . Let's take any 2 points in the graph. (-2,-1) and (1,5)

Now, we know that the slope is 2.

b

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
