Your friend claims there is an easier way to find the length of a segment than the Distance Formula when the x-coordinates of the endpoints are equal. He claims all you have to do is subtract the y-coordinates. In the image above, this would be like two hot air balloons directly in line with each other with one below and one above. Do you agree with his statement? Explain your reasoning. You may include an image, a graph, or work to help support your argument
