On graph paper, plot
is the midpoint of , is the midpoint of , and is the midpoint of , find the coordinates of .
When finding the midpoint remember to calculate the average of the
-coordinates and the average of the -coordinates for the two points.
What fraction of the distance from
to is ?
Draw a slope triangle for
and a slope triangle for , then compare their side lengths.
Use the ratio from part (b) to find the coordinates of point
