finding missing endpoints: is there a way to do it algebraically?
http://www.youtube.com/watch?v=d51p_8xQQZ0
so you can draw a number line to see how far each number is from each other, but is there a faster way to do it?

Best ResponseYou've already chosen the best response.0we can do both for first coordinate solve \[\frac{x9}{2}=8\] and for second solve \[\frac{y1}{2}=14\]

Best ResponseYou've already chosen the best response.0because midpoint you use \[\frac{x_1+x_2}{2}\] for the first coordinate and \[\frac{y_1+y_2}{2}\] for the second. so if you know the answer you can find the first or second coordinate

Best ResponseYou've already chosen the best response.0yes i "subtracted" because both were negative. if they had been positive i would have added.
