How do you right an equation for a slope?

The equation for slope is m = (y2 - y1)/(x2 - x1)

Step-by-step explanation:

In the above equation, m is the slope. So in order to find it, you need two points on the line. Those points would be (x1, y1) and (x2, y2). You can then stick their values in for the variables and solve for m (which is your slope).

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.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
