what are the two points and what is your answer?
The 2 points are A -1,321 and B 517. My answer is 919
how is point B 517?
it should be an ordered pair
points are of the form (x,y)
No the question issnt asking for ordered pairs. It's a line with points so it'll be like|dw:1379387454390:dw|
and then its asking for the distance from either endpoint to the midpoint
oh it's on a number line, i see
yes it is
I thought when you wrote out A -1,321 you meant (-1,321) or something
the distance from A -1,321 and B 517 on the number line is found by subtracting 517 - ( -1321) 517 + 1321 1838
so the distance from A to B is 1838 units
cut that distance in half to get your answer
Correct.Okay, when I divide it by 2 I get 919
What would the midpont be?
add the two values, then divide by 2 to get the midpoint
oh, so instead of subtracting like we did here, we add!1 ohhhhh
yep, that's correct because the formula is M = (x1+x2)/2
Okay, I have another question if you dont mind
What would the midpoint of Line AB is at -421 and A is at 32?
I got 194.5 but im not sure
good, but it's negative
since -421 is a much bigger number in the negative direction
but before we were taught that we would always put the absolute value of that number
hmm you're probably thinking distance and not midpoint
yeahhh! oh so when finding the midpoint the number COULD be negative, correct?
yes midpoints can easily be negative
okay, thank you:) i appreciate it
