To graph a line, we need a point and a slope. In this case, we have been given the point (3,2), but we are told that the slope is undefined. This means that the line is vertical, since that is the only line with undefined slope.
To graph the line, start at the point (3,2) and then draw a straight vertical line like the following:
Undefined slope means a vertical line. We want it to go through the point (3, 2).
That means for every y value, they share the same x value.
Draw a vertical line running through the point 3.
