Question

Find the coordinates of the midpoint of a segment with the endpoints
(16,5) & (28, -13).

ddcamp · Answer

Midpoint formula:
$$M = \left( \frac{ x₂-x₁ }{ 2 }, \frac{ y₂-y₁ }{ 2 } \right)$$

anonymous · Answer

what did you get when you solved? i didnt get it

ddcamp · Answer

So you have your 2 points, (x₁,y₁) and (x₂,y₂), or in this problem (16,5) and (28,-13)

x₁ = 16
x₂ = 28
y₁ = 5
y₂ = -13

Just plug those values into the midpoint formula and you'll get the point M

but i got 6,9 but thats not in the answer choices

ddcamp · Answer

Is the 9 positive or negative?

anonymous · Answer

-9

ddcamp · Answer

It should be (6,-9), at least, that's what I got.

anonymous · Answer

i got that too but its not one of the choices

ddcamp · Answer

<facepalm> I copied the formula wrong, it should be adding, not subtracting.

anonymous · Answer

okay so what did you get?
