Sagot :
Answer:
Below
Step-by-step explanation:
a.
5x + y = 15
b.
I can't put a graph here, but it is a straight line through (3, 0) and (0,15).
c.
The ordered pairs on the graph represent the possible combinations of 5 dollar bills (x-coordinate) and 1 dollar bills (y-coordinate) you can have summing to $15.
The valid pairs are: (3, 0), (2, 5), (1, 10), (0, 15)
d.
If you have 2 $5 bills, you will have 5 $1 bills (from the pair (2, 5)).
e.
If you have 10 $1 bills, you will have 1 $5 bill (from the pair (1, 10)).
f.
The x-intercept is (3, 0); this ordered pair is when we have 3 $5 bills and no $1 bills.
The y-intercept is (0,15); this ordered pair is when we have 15 $1 bills and no $5 bills.
