A TI-84 graphing calculator is a handheld calculator that you can use for statistics, algebra and calculus. With the TI-84, there’s no need to draw graphs by hand: The graphing screen enables you to chart and draw graphs with the push of a button or two. You aren’t limited to continuous functions – you can plot ordered pairs on the TI-84 using the Lists utility. Ordered pairs are used to plot points on an XY coordinate graph and take the form (x,y).
