Find the equation of the line shown.

y = -0.5x - 2

Step-by-step explanation:

y = mx + b

m is slope, change in y / change in x

slope = 1/2

b is y intercept

line intersects y axis at negative 2

therefore the equation is y = -0.5x - 2

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.
