Answer: -53, 53
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
, 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,
=
![(655-930)/(6-1)](https://img.qammunity.org/2021/formulas/mathematics/high-school/y9vr2z3dg8m9e7yz7e326iwhpf8srtko2b.png)
This simplifies to
=
![(-265)/(5)](https://img.qammunity.org/2021/formulas/mathematics/high-school/8puzfoqiij3w9cs34zxnwgwbu5l1bukwyn.png)
which is -53.
Therefore, the slope is -53, so the balance decrease by $53 each month.
