Use a graphing utility to approximate all points of intersection of the graph of the system of equations. Round your results to three decimal places. Verify your solutions by checking them in the original system. $\left\{\begin{aligned} 7 x+8 y & =24 \\ x-8 y & =8\end{aligned}\right.$

Key Concepts

System of Equations

A system of equations involves finding values for the variables that satisfy all equations simultaneously. It often represents multiple conditions or relationships that are all true at one point, and solving the system gives the common solution or solutions that satisfy every equation in the system.

Graphical Interpretation

Graphing the equations provides a visual method to find solutions by identifying the points where the graphs intersect. Each equation is represented as a line or curve on a coordinate plane, and their intersection point(s) corresponds to the solution of the system.

Intersection Point

The intersection point of the graphs of two equations is the point where both equations are satisfied simultaneously. This point represents the values of the variables that are common to both equations, thus solving the system.

Approximations and Rounding

In many practical applications, especially when using graphing utilities, the solutions obtained are approximations. Rounding these numerical approximations to a specified number of decimal places makes the results more concise and easier to communicate while still maintaining reasonable accuracy.

Solution Verification

Verification involves substituting the obtained solutions back into the original equations to ensure that they satisfy every equation. This step is essential to confirm the correctness of the approximated intersection point and to validate the overall solution process.
