To use a graphing calculator to solve a system of equations, you typically follow these steps:
1. **Enter the Equations**: Input each equation into the graphing calculator. Make sure the equations are in a form that the calculator can handle (like \(y = mx + b\) for linear equations).
2. **Graph the Equations**: Use the graphing function to plot the equations. The calculator will display the graphs of both equations on the same coordinate plane.
3. **Find the Intersection Point**: The solution to the system of equations is the point where the two graphs intersect. Use the "calculate" or "intersection" function (often located in the 'Calc' menu) to find the exact coordinates of the intersection point.
Now, regarding your specific options:
A. **Is every point on the second line**: This option is not accurate in the context of solving a system of equations. Only the points on the second line are solutions to the second equation.
B. **Is every point on the first line**: This option is also not accurate. Only points on the first line are solutions to the first equation.
C. **Can be found where the two lines intersect**: This is the correct option. The solution to the system of equations is indeed the point(s) where the two lines intersect, indicating the values of the variables that satisfy both equations simultaneously.
So, the correct answer is **C**: The solution can be found where the two lines intersect.
