Question

Find the midpoint of the segment with endpoints of (-12, -9) and (2, 10) and enter its coordinates as an ordered pair. if necessary, express coordinates as fractions, using the slash mark ( / ) for the fraction bar.

Answer 1

We're looking at the difference between the coordinates here i.e.
`x_1-x_2 \\ y_1-y_2`

Therefore, 2-(-12)=14 and 10-(-9)=19
Halving both of these gives 7 and 9.5, since the difference gets you all the way along the line segment, so halving it will get you to the midpoint.

Adding 7 to -12 gives -5, adding 9.5 to -9 gives 0.5 (1/2)

Putting these together, this gives the coordinates (-5,1/2)
