Question

has endpoints at -2 and 12. What is the coordinate of its midpoint?

Answer 1

differnce bet ween points so in this case
-2-12
then divide that by 2 and you will hav ea mid point coodrinate but you need an x and y component you have youonly given on coordinate

Answer 2

-2 to 12

if we add 2 to each end

-2 to 12
+2 +2
---------
0 to 14

what is half of 14?

Answer 3

7?

Answer 4

correct so ... lets put that in and readjust it back

0 to 7 to 14
-2 -2 -2
-----------
-2 to 5 to 12

Answer 5

we get the same thing by using the midpoint formula:
\[\frac{first+last}{2}\]\[\frac{-2+12}{2}=10/2 = 5\]
