Answer: -53, 53
Step-by-step explanation:
It’s asking for the slope first, so let’s find it:
First, let’s determine our coordinates.
We have (1, 930) and (6, 655).
The slope equation is [tex]\frac{y_1 - y_2}{x_1 - x_2}[/tex], so let our (1, 930) be our x_1 and y_1, and (6, 655) be our x_2 and y_2.
So, we have,
= [tex]\frac{655-930}{6-1}[/tex]
This simplifies to
= [tex]\frac{-265}{5}[/tex]
which is -53.
Therefore, the slope is -53, so the balance decrease by $53 each month.
