The correct answer is:

The point at which the lines intersect.

In a system of linear equations, the solution is represented by the point where the two lines intersect on the graph. This point gives the values of $x$ and $y$ that satisfy both equations simultaneously.

Here are some follow-up questions:

1. How do you graphically solve a system of linear equations?
2. What does it mean if two lines never intersect on a graph?
3. How do you determine the slope and y-intercept of a line from an equation?
4. What are the different types of solutions a system of linear equations can have (one solution, no solution, infinitely many)?
5. How do you check your solution after graphing the system?

Tip: When graphing two linear equations, always make sure to label the axes and plot the lines accurately to ensure the intersection point is correct.
