Part A (describing the number line):
-Draw a horizontal line
-Put a zero in the middle of the line
-Put -1 to -4 on the left of 0
-Put 1 to 4 on the right of 0
-Draw a dot at -2.75 and label John
-Draw a dot at -3 and label Cheryl
Part B: Cheryl owes the bank more than John. |-2.75| |-3.00| The absolute values are never negative so: 2.75 & 3.00. 3.00 is greater than 2.75.

Answer:
A) See attached.
B) Cheryl owes the bank more.
Step-by-step explanation:
Given account balances:
- John: -$2.75
- Cheryl: -$3.00
- Andrew: $2.75
(Andrew has as much savings in his account as the amount John owes).
Part A
- Draw a straight, horizontal line with arrows on both ends.
- Place a tick in the center of the line and label it zero.
- Draw 4 evenly spaced ticks either side of the zero.
- Number the ticks to the right of the zero 1, 2, 3 and 4.
- Number the ticks to the left of the zero -1, -2, -3, and -4.
- Mark -2.75, -3 and 2.75 on the number line.
- Label the marks with John, Cheryl and Andrew.
(See attached number line).
Part B
The absolute value of a number is its positive numerical value.
To calculate how much John and Cheryl owe the bank, take the absolute values of their account balances:
- John: |-2.75| = 2.75
- Cheryl: |-3.00| = 3.00
As 3.00 > 2.75, Cheryl owes the bank more.
