Label each point in the coordinate plane with the letter that represents its coordinates.

Coordinate plane, horizontal axis, negative 10 to 10 by ones, vertical axis, negative 10 to 10 by ones. One point is 8 units left and 4 units up from the origin. A point is 3 point 5 left and point 2 up from the origin. A point is three units right and 2 units up from the origin. A point is 7 units right and between 5 and 6 units below the origin.

The graph shows the balance in a bank account over a period of 14 days. The axis labeled represents account balance in dollars. The axis labeled represents the day.

Coordinate plane, horizontal axis, d, 0 to 14 by ones, vertical axis, b, negative 150 to 400 by fifties. Points at (1 comma 350), (2 comma 350), (3 comma 350), (4 comma 275), (5 comma 275), (6 comma negative 50), (7 comma 110), (8 comma 110), (9 comma 110), (10 comma 110), (11 comma negative 90), (12 comma 25), (13 comma 25).

1. Estimate the greatest account balance. On which day did it occur?
2. Estimate the least account balance. On which day did it occur?
3. What does the point tell you about the account balance?
4. How can we interpret in the context?

The coordinate plane shows the high (x) and low (circle) temperatures in Nome, Alaska, over a period of 8 days. The axis labeled represents temperature in degrees Fahrenheit. The axis labeled represents the day.

Coordinate plane, origin O, horizontal axis, d, 0 to 9 by ones, vertical axis, T, negative 6 to 28 by twos. Red points at (one comma 28), (2 comma 26), (3 comma 21), (4 comma 11), (5 comma 13), (6 comma 17), (7 comma 7), (8 comma 2). Blue points at (1 comma 28), (2 comma 20), (3 comma 11), (4 comma 3), (5 comma 10), (6 comma 7), (7 comma negative 3), (8 comma negative 1).

1. What was the warmest high temperature?
2. What was the coldest low temperature?

3. 1. On which day(s) did the largest difference between the high and low temperatures occur? What was this difference in degrees Fahrenheit?

   2. On which day(s) did the smallest difference between the high and low temperatures occur? What was this difference in degrees Fahrenheit?
