Gotta grab lunch. Look up the formula for the midpoint. If you can't find it, ask in chat for help. But don't post the question. @563blackghost may be able to help.

563blackghost:

@johnnn i can help ^-^

563blackghost:

Uhhh I can't do that. One of the terms is to provide a full detailed explanation that will help you learn your question. I can not give direct answers.

johnnn:

okay so can u help?

563blackghost:

Yes :D We need to use the mid-point formula. Mid-Point Formula: |dw:1519771097625:dw|

563blackghost:

You would need to plug the points in this formula. The first point is `(3,-4)` and the second point is `(5,-5)`. Remember the format of a point is \(\bf{(x,y)}\). Can you plug this?

johnnn:

is the answer C?

563blackghost:

Not quite.

johnnn:

B?

563blackghost:

Plug the points. \(\Large\bf{(\frac{-3+5}{2},\frac{-4+-5}{2})}\)

johnnn:

the answer is A

563blackghost:

yes

johnnn:

thanks!!!
