Which step comes last when using the divide-center method to find the line on a scatter plot?
a. approximate the center of the cluster located on the left side of the line, and repeat for the right side of the line.
b. connect the two centers to produce the trend line.
c. disregard outliers.
d. draw a vertical line so that each side has the same number of data points.

step-by-step explanation:

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)
