Midpoint is closely tied with 'averages'

So, the x-coordinates are -3 and -8, what's their average?

anonymous · Answer

@terenzreignz I'm sorry but I don't understand. X value of mid point = average of x-coordinate?

terenzreignz · Answer

Precisely ^^

yanasidlinskiy · Answer

The midpoint formula is:
((x1 + x2)/2, (y1 + y2)/2)

Hold on one sec let me sub the numbers in... @terenzreignz @YanaSidlinskiy

anonymous · Answer

Wait I did something wrong... i got -5 both times.. @terenzreignz

terenzreignz · Answer

This is why you should show your steps...

Could you show me how you got -5?

anonymous · Answer

Okay I did (-3+-8)/2=-5.5 , (-7+-4)/2=-5.5   :/ @terenzreignz

terenzreignz · Answer

Neither of which are -5 :P

Can you write -5.5 in fraction form? ^_^

anonymous · Answer

11/2? @terenzreignz

terenzreignz · Answer

*negative
And yes, apart from that, you're right.

Do you know the answer now? ^_^

anonymous · Answer
