Select the correct answer.
Which data set has the greatest spread for the middle 50% of its data?
OA. {18, 13, 22, 17, 21, 24}
B. {17, 19, 22, 26, 17, 14}
OC. {13, 17, 12, 21, 18, 20}
D. {18, 21, 16, 22, 24, 15}

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)
