Introduction

The ALEKS graphing calculator is a powerful tool for solving systems of equations. In this article, we will explore how to use the ALEKS graphing calculator to solve a system of linear equations. We will use the following system of equations as an example:

y=−10x−8{ y = -10x - 8 } y=−x−4{ y = -x - 4 }

Step 1: Enter the Equations into the ALEKS Graphing Calculator

To enter the equations into the ALEKS graphing calculator, follow these steps:

  1. Open the ALEKS graphing calculator and select the "Graphing" tab.
  2. Click on the "Equations" button and select "Enter Equation".
  3. Enter the first equation, y = -10x - 8, into the equation editor.
  4. Click on the "Add Equation" button and enter the second equation, y = -x - 4, into the equation editor.

Step 2: Graph the Equations

Once you have entered the equations into the ALEKS graphing calculator, you can graph them by clicking on the "Graph" button. The graph will display the two lines represented by the equations.

Step 3: Find the Intersection Point

To find the intersection point of the two lines, you can use the "Intersection" tool in the ALEKS graphing calculator. To do this, follow these steps:

  1. Click on the "Tools" button and select "Intersection".
  2. Select the two equations that you want to find the intersection point for.
  3. The ALEKS graphing calculator will display the intersection point, which is the solution to the system of equations.

Step 4: Round the Solution to the Nearest Hundredth

Once you have found the intersection point, you can round the solution to the nearest hundredth by using the "Round" tool in the ALEKS graphing calculator. To do this, follow these steps:

  1. Click on the "Tools" button and select "Round".
  2. Select the solution that you want to round.
  3. The ALEKS graphing calculator will display the rounded solution.
