4. Hightop Roofing was $3765 in the "red" (owed creditors this amount) at the end of
gulaghasi [49]

The negative sign shows that they still owed $5000 to the creditors which shows a loss of money between June and December.

Step-by-step explanation:

Amount owed at the end of June = $3765

Amount owed at the end of December = $8765

As Hightop Roofing owed creditors the amount, therefore, we will consider the amount as negative, therefore,

Amount in June = -3765

Amount in December = -8765

To see the difference, we will subtract the amount owed in June from the amount owed in December.

Difference=(-8765)-(-3765)\\Difference=-8765+3765\\Difference=-5000

The negative sign shows that they still owed $5000 to the creditors which shows a loss of money between June and December.

Keywords: difference, loss

b is the y-intercept and m is the slope
