Final answer:
One advantage of graphing equations is that it provides a visual representation of the solution, while one disadvantage is that it can be time-consuming and imprecise.
Step-by-step explanation:
One advantage of solving a system of equations by graphing is that it provides a visual representation of the solution.
By plotting the equations on a graph, you can easily see where the lines intersect, which gives you the solution to the system of equations.
One disadvantage of graphing is that it can be time-consuming, especially if the equations are complex.
Drawing accurate graphs and determining the intersection point can require precision and patience.
It may also be difficult to get an exact solution if the intersection point is not on grid lines.
