This is a linear graphing calculator (A decent one at best) * When the green flag is pressed there will be some questions that ask for the slope and y intercept of the line. * This calculator can only do linear lines and cannot do lines with an undefined slope. * To find if a certain point is on the current line you press the space bar and enter the X value of the point and then the Y value. * To add a new line you have to press the up arrow. This will ask you the same questions as the first line (slope and y intercept) * When you have created a new line it is the only line that you can find points for.
All the tic marks are 1 whole number apart so lines with large slopes wont work well. The find a point feature will still work even though the line cannot be graphed right. To clear all the lines press the green flag again.
