Introduction

In mathematics, a system of linear equations is a set of two or more linear equations that involve the same set of variables. Solving a system of linear equations is a fundamental concept in algebra and is used to find the values of the variables that satisfy all the equations in the system. In this article, we will use a graphing tool to solve a system of two linear equations and find the coordinates of the solution.

Graphing Tools and Their Applications

Graphing tools are software or online applications that allow users to visualize and analyze mathematical functions and equations. They are widely used in mathematics, science, and engineering to solve problems and make predictions. Graphing tools can be used to graph linear and non-linear equations, find the intersection points of two or more graphs, and solve systems of linear equations.

The System of Linear Equations

The system of linear equations we will be solving is:

\begin{array}{l} y = 2.85x - 4 \\ y = 5.3x + 1.6 \end{array}

This system consists of two linear equations with two variables, x and y. The first equation is y = 2.85x - 4, and the second equation is y = 5.3x + 1.6.

Graphing the Equations

To solve the system of linear equations using a graphing tool, we need to graph the two equations on the same coordinate plane. We can use a graphing calculator or an online graphing tool to graph the equations.

Graphing the First Equation

The first equation is y = 2.85x - 4. To graph this equation, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. The slope of the first equation is 2.85, and the y-intercept is -4.

Graphing the Second Equation

The second equation is y = 5.3x + 1.6. To graph this equation, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. The slope of the second equation is 5.3, and the y-intercept is 1.6.

Finding the Intersection Point

The intersection point of the two graphs is the solution to the system of linear equations. To find the intersection point, we need to find the point where the two graphs intersect.

Using a Graphing Tool to Find the Intersection Point

We can use a graphing tool to find the intersection point of the two graphs. To do this, we need to enter the two equations into the graphing tool and adjust the window settings to find the intersection point.

Finding the x-Coordinate

Once we have found the intersection point, we can find the x-coordinate by reading the value from the graph or by using the graphing tool to find the x-coordinate.

Finding the y-Coordinate

Once we have found the x-coordinate, we can find the y-coordinate by substituting the x-coordinate into one of the original equations.

Rounding the Coordinates

The problem asks us to round each coordinate to the nearest hundredth. To do this, we need to round the x-coordinate and the y-coordinate to the nearest hundredth.

Conclusion

In this article, we used a graphing tool to solve a system of two linear equations and find the coordinates of the solution. We graphed the two equations on the same coordinate plane, found the intersection point, and rounded the coordinates to the nearest hundredth. The x-coordinate is 1.43, and the y-coordinate is 3.43.

Discussion

The system of linear equations we solved in this article is a simple example of a system of linear equations. In real-world applications, systems of linear equations can be much more complex and involve multiple variables and equations. Graphing tools are a powerful tool for solving systems of linear equations and can be used to visualize and analyze complex mathematical functions and equations.
