Answer 2

Okay so here you will have to find the midpoint of AB and BC, and then use the distance formula to find the length of the segment MN.

Answer 3

For AB, you have

(1 + 9) / 2 =?

and

(5 + 7) / 2 =?

Answer 4

That gives you the midpoint, or point M of the segment.

Answer 5

Now for BC

(9 + 7) / 2 =?

and

(7 + 13) / 2 =?

And now you have point N.

Answer 6

Got the points?

Answer 7

Yes

Answer 8

You should have M(5, 6) and N(8, 10)

Plug these into the distance formula d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Answer 9

I got 5
