Age of Senators The average age of senators in the 108th Congress was 63 years. If the standard deviation was 13.5 years, find the z-scores corresponding to the oldest and youngest senators of age 84 and 43. Round z scores to two decimal places. Part: 0 / 20 of 2 Parts Complete The -score corresponding to the oldest senator of age 84 is
.

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)
