Find the midpoint of the segment with endpoints of (1, 4) and (-2, 6) and enter its coordinates as an ordered pair. If necessary, express coordinates as fractions, using the slash mark ( / ) for the fraction bar.

OpenStudy (whpalmer4):

The midpoint of a line segment is located at the average of the x coordinates and the average of the y coordinates.

OpenStudy (anonymous):

but how do find the answer

OpenStudy (whpalmer4):

like I told you: take the average of the x coordinates. that's the x coordinate of the midpoint. take the average of the y coordinates. That's the y coordinate of the midpoint.

OpenStudy (whpalmer4):

you know how to average two numbers, right?

OpenStudy (whpalmer4):

add them together, then divide by 2

OpenStudy (anonymous):

add 1, 4, -2 and 6?

OpenStudy (whpalmer4):

you have two points. \((1,4)\) and \((-2,6)\) What are the x-coordinates?

OpenStudy (whpalmer4):

Hint: \((x,y)\)

OpenStudy (anonymous):

can you give me an example

OpenStudy (whpalmer4):

I did. \((x,y)\) is an example. The x-coordinate is \(x\). The y-coordinate is \(y\).

OpenStudy (whpalmer4):

So in the two points at the ends of our line segment, what are the respective x-coordinates?

OpenStudy (anonymous):

is it (1 -2)/2, (4+6)/2 = (1.5,5)

OpenStudy (whpalmer4):

1-2 = ?
