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

I thought when you wrote out A -1,321 you meant (-1,321) or something

oh no!

2
the distance from A -1,321 and B 517 on the number line is found by subtracting
517 - ( -1321)
517 + 1321
1838

2
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?

*midpoint

2
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

2
yep, that's correct because the formula is
M = (x1+x2)/2

Okay, I have another question if you dont mind

1
What would the midpoint of Line AB is at -421 and A is at 32?

1
I got 194.5 but im not sure
jim_thompson5910
Best Response
You've already chosen the best response.
2
good, but it's negative
jim_thompson5910
Best Response
You've already chosen the best response.
2
since -421 is a much bigger number in the negative direction

1
but before we were taught that we would always put the absolute value of that number

2
hmm you're probably thinking distance and not midpoint

1
yeahhh! oh so when finding the midpoint the number COULD be negative, correct?

2
yes midpoints can easily be negative
