Answer:

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

Step-by-step 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=\frac{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=\frac{2000-2400}{12-4}\\ \\m=\frac{-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.

You know Clara already has 10 pages, and that 15 will be written per month. Therefore, the equation is p=15m+10

To find the answer for 5 months simply substitute m

15(5) + 10

75+10
