From the equation, the y intercept is simply determined by setting x = 0. The x intercept(s) are generally much harder to find: you will need to find the solutions of y = 0 [or f(x) = 0]. From the graph the intercepts are the coordinates of the points at which the graph crosses the axes.

They will be on the horizontal x axis of the graph (look for the x-intercepts).
One.
Draw the axes. Plot the two intercepts. Draw a line connecting the two points
Graph the equation then find the x intercepts.
