In a two-dimensional coordinate system, the line defined by the equation $$y = mx + b$$ intersects the x-axis at the point \( (p, 0) \). Given that the slope of the line is $$m = -2$$ and the y-intercept $$b = 6$$, you are tasked with finding the value of $$p$$ where this line intersects the x-axis.
To find the x-coordinate of this intersection, recall that the y-coordinate is zero. Hence, what is the value of $$p$$?
