(these all have a fixed shipping fee)
it costs $33 to ship 2 items of clothing
$48 for 3 items of clothing
how much for 1 item of clothing (pretend these are all the same items)
make a y=mx+b equation and label what m and b stand for
deleted, one question per post.
so make a table
you have two values so far
x | y
$33 | 2 items
$48 | 3 items
then what's 1 item?
then plot (33,2) (48,3) and make a line
and at the one mark on the y axis that's your answer
