Question

Please, can someone help me!!

I need to graph a scatter plot involving the height and arm span of 6 people but I don't have the software to do it and I can't download it either, I don't know why? But anyway, the points are:

66 inches tall arm spam 65,
57 inches tall, arm span 58 inches.
61 inches tall, arm span 61.5,
75 inches tall, arm span 75.
62 inches tall, arm span 61.75,
63 inches tall, arm span 64.

I also have to determine the line of best fit. So if you could tell me which two points you used to draw the line of best fit, you would be a real life saver!!
