Answer 1

The slope is
`-50`. The slope means that the amount of money in the account is decreasing at a rate of $
`50` every week.

Explanation:

Given coordinates are
`(4,2400)\ and\ (12,2000)`

We need to find the slope of the graph, and explain what does slope means for this graph.

The formula for computing slope
`(m)` is

`m=(y_2-y_1)/(x_2-x_1)`

Where
`(x_1.y_1)` and
`(x_2,y_2)` are the point on the line.

Let us plug points
`(4,2400)\ and\ (12,2000)` in the equation

`m=(2000-2400)/(12-4)\\ \\m=(-400)/(8)\\\\m=-50`

Here, the negative sign of slope
`(m)` represents that the value of the function (budget) is decreasing, with an increase in time (week).

The slope is
`-50`. The slope means that the amount of money in the account is decreasing at a rate of $
`50` every week.
