Answer

Using a graph to solve an equation involves visualizing the functions and finding their intersection points.

When you have an equation like $f(x) = g(x)$ , you can draw the graph of $y = f(x)$ and the graph of $y = g(x)$ on the same set of axes.
The x-coordinates of the points where these two graphs intersect are the solutions (or roots) of the equation $f(x) = g(x)$ .
If you are solving for $f(x) = 0$ , you would look for the points where the graph of $y = f(x)$ crosses the x-axis (where $y=0$ ).
