Chapter 12: Q.12.13 (page 714)

Due to erosion, a river shoreline is losing several thousand pounds of soil each year. A linear equation that expresses the total amount of soil lost per year is y=12,000x.

How many pounds of soil does the shoreline lose in a year?

Short Answer

Expert verified

The pounds of soil that the shoreline loses in a year is 12,000.

Step by step solution

01

Given information

Given in the question that a linear equationy=12,000x.

02

Solution

The general linear equation formula is,

y=a+bx

Here,

a=y-intercept

b=slope

The y is a dependent and x is an independent variable.

In the question, y is the soil lost in the pound and x is the time or year.

Now the equation is

y=12,000x

Here the slop is 12,000because it means that the expected loss of soil in the pound if the year is increased by one.
