The slope of a line can be calculated using the formula:
slope = (change in y) / (change in x)
Given the points (1, 4) and (1, 1), we can see that there is no change in x. Since the value of x remains constant at 1, the change in x is equal to 0. Therefore, the slope of the line is undefined (or sometimes referred to as "no slope" or "vertical line").
