If you have 2 points on the line (x1,y1) and (x2,y2), then the slope is (y1 - y2)/(x1 - x2). For a vertical line, x1 = x2. This makes the slope formula (y1 - y2)/(x1 - x1) = (y1 - y2)/0
Since division by zero is undefined, the slope is also.

as a results of fact the function must be in terms of y, you won't be in a position to truly graph x = 2. that's no longer a function, rather as a results of fact the comparable value of x has distinctive values of y. That stated, you are able to "trick" the TI-80 4 into graphing a vertical line. Graph y=(x-2)/0.000000000000001 for the graph of x=2. it sounds as though as a vertical line on your calculator, yet in actuality it is basically a graph with an extremely, very steep slope.

the slope is undefined because slope is rise over run and if the rise is 0 then and the run is infinitive then you cant identify a direct slope.
