The document discusses graphing functions and linear equations. It explains that the x-axis is the horizontal line on a graph and the y-axis is the vertical line. Intercepts are where the graphed line touches the x-axis and/or y-axis. It shows how to solve the equation -18x+6y=18 for y and writes the equation as y=3x+3. Finally, it has the student make a table of x and y values to graph the line described by the function y=3x+3.
