(a) the cost of the fruit in $2 per lb = slope of the line
a cost of $10 ( the height of the vertical axis) and a weight of the strawberries ( the corresponding point on x axis)
so the lope is 10/5 = 2 that is $2 per lb of strawberries
cost = 2w where w = weight of strawberries in pounds
(b) in the same way cost of each lb of blueberries = 10/7 = $ 1.43
cost = 10w/7 where w = weight of blueberries in lbs.
c) blueberries are cheaper ( $1.43 / lb against %1 per lb for strawberries)
i tried my best if i'm right if i'm wrong i am so sorry.but if i am right plzzz mark brainliest: )
