Question

Find the coordinates of the midpoint between point A(18, -6) and the origin.

Answer 1

Use the midpoint formula attached below.

Take the coordinates of the origin and the coordinates of A. Average the two x values and then average the two y values to get the coordinates of the midpoint. Let me know what you get. Okay?

Answer 2

i don't get it at all/:

Answer 3

What are the coordinates of the origin?

Answer 4

idk? all i know is what that question gave me?

Answer 5

Look up the coordinates of the origin in your text. The origin is the point in the plane where the x axis meets the y axis.

Look at the diagram here: http://www.mathopenref.com/coordintro.html

Answer 6

0,0?

Answer 7

Yes.

The two points that determine the segment of which we want the midpoint are (0,0) and (18,-6). So, look at the midpoint formula posted above.

I'll do the x coordinate of the midpoint and then you do the y coordinate of the midpoint, okay? @Kitteh

Answer 8

9,-3?

Answer 9

That is what I got.
