For this inquiry, we are presented with a graph, and we're tasked with determining the x-coordinate of where the two lines intersect.
An examination of the graph indicates that the input value is around 3.3.
In the graph,

To derive g(x), we need the slope and y-intercept.
The slope represents the ratio of vertical change to horizontal change.
In this case, the rise is 3 units and the run is 2 units. The line intersects the y-axis at -2.
Thus, the equation for g(x) becomes

Next, we will perform

Substituting the values of both functions will yield

By adding 2 to both sides, we have

We will apply cross multiplication


Thus, the approximate input value is 3.3.
