Question

The equation of the trend line shown is = − 20/9 + 900. Use the trend line to predict the number of minutes it will take Mrs. Thompson’s class to complete the 900 pages.

Answer 1

We want to use a linear equation to predict the time that it would take to read 900 pages.

The solution is: Mrs. Thompson's class will need 405 minutes to complete the 900 pages.

Now let's see how we got the solution:

Sadly, you didn't write the variables in the equation, so I will assume that the linear equation is:

$y = -\frac{20}{9}*x + 900$

Where:

• y is the number of pages left.
• x is the time in minutes.

To find the time it would take to read the 900 pages, we need to find the value of x such that y = 0, this means that we need to solve:

$0 = y = -\frac{20}{9}*x + 900\\\\0 = -\frac{20}{9}*x + 900$

The solution will be given by:

$0= -\frac{20}{9}*x + 900\\\\\frac{20}{9}*x = 900\\x = (9/20)*900 = 405$

This means that Mrs. Thompson's class will need 405 minutes to complete the 900 pages.
