Ix. com/math/grade 7/identify-proportional-relationshi ps-by-graphing. Tim is crocheting a scarf as a birthday present for his sister. He started the scarf yesterday
and needs to finish it today before his sister's birthday party. After 6 minutes of crocheting
today, the scarf is a total of 8 inches long. After 10 minutes, the scarf is a total of 10 inches
long.
In this relationship, x represents the amount of time (in minutes) Tim spends
crocheting
today, and y represents the total length of the scarf (in inches).
Graph two points for this relationship and the line passing through them.

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
