A study was commissioned to find the mean weight of the residents in certain town. The study found the mean weight to be 183 pounds with a margin of error of 8
pounds. Write a confidence interval for the true mean weight of the residents of the
town.

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)

answer: 0.26

i used the calculator on google

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
