A clothing business finds there is a linear relationship between the number of shirts, n, it can sell and the price,
p, it can charge per shirt. In particular, historical data shows that 1000 shirts can be sold at a price of $34, while
4000 shirts can be sold at a price of $22. Find a linear equation in the form p(n) = mn + b that gives the price
p they can charge for n shirts.

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)

nope.   happens to me as well.
