Biff hit homeruns every year he played. Four times he hit 12, twice he hit 15 and other years Biff hit 6, 11, 19, and 20 homeruns. What was the mean number of homeruns that Biff hit per year? How did you find this?

12 is the mean

Step-by-step explanation: Just find the middle number

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
