Question

Can someone help me find the midpoint?

Answer 1

(6,-2.5)

Explanation:

The formula for the midpoint between two points is:

`((x_(1) + x_(2))/(2),(y_(1)+y_(2))/(2))`

Now we substitute

We have than (9, -1) is
`(x_(1), y_(1))` and (3, - 4) is
`(x_(2), y_(2))`

So:

`(((9) + (3))/(2),((-1)+(-4))/(2))\\\\(-1) + (-4) = -5\\9 + 3 = 12\\`

So, we have:

`((12)/(2), (-5)/(2))\\\\12 / 2 = 6\\-5 / 2 = -2.5\\\\(6, -2.5)`

(6,-2.5)

I can do a graphic explanation if you want.
