#### More specific sub-standards

Explain why the ๐น-coordinates of the points where the graphs of the equations ๐บ = ๐ง(๐น) and ๐บ = ๐(๐น) intersect are the solutions of the equation ๐ง(๐น) = ๐(๐น); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where ๐ง(๐น) and/or ๐(๐น) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.

Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).
