ABSTRACT:
A graphing calculator (10) having manual line drawing capability. The calculator (10) is programmed to receive data representing the begin point and end point of a line (FIGS.7and8), and to then draw a line that includes these points (FIG.9). The display includes a display of the line equation (FIG.9). The slope and y-intercept of the line may be adjusted using cursor direction keys. As the line is adjusted, it is redrawn and the line equation is re-calculated and displayed (FIG.10).
