so -8.726646 radians
The slope is y/x 20/4=5 meaning as it rises 5 feet it will horizontaly change by 1 foot
Step-by-step explanation:
Find the unit rate of each pair of socks for the dozen. 12/9=1.3333
so then multiply 18 by 1.33 to get 23.92. So you could sell the 18 pair pack of socks for anything less than $23.92
Hope this helps ^-^
