Question

Can anybody help me on this please

Answer 1

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
`(y_1 - y_2)/(x_1 - x_2)`, 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)`

This simplifies to

=
`(-265)/(5)`

which is -53.

Therefore, the slope is -53, so the balance decrease by $53 each month.
