1) Li Na is saving money. Her parents gave her an amount to start, and since then she has been putting aside a fixed amount each week. After six weeks, Li Na has a total of
$82. Fourteen weeks from the start of the process Li Na has $118.
a) using x for the number of weeks and y for the amount in savings (in dollars), construct
a linear function that describes the relationship between the number of weeks and the
amount in savings.

Answer : Y^2 - Y^1 over X^2 - X^1 covert the points given
4.5 is the slope
Y=Mx+b
Y=4.5x+55
B=55
