The graph shows the pizza orders taken at a pizza shop during lunchtime one day.
which statements are true?
choose exactly two answers that are correct.

a) half of the delivery orders cost less than $20.
b) one-fourth of the carryout orders cost $20 or more.
c) fewer than 25% of the orders costing $20 or more were carryout orders.
d) there were twice as many delivery orders as carryout orders.

f is the midpoint of

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)
