Question 1063647: Another problem that I don't know where to start:
Given the points P1 (-4,-1) and P2 (8,3). Find the coordinates of the point R(x,y) on P1P2 (this has a line over it and the 1 and 2 are subscript) so that the ratio P1R : RP2 = 3:1 (1 and 2 are subscript).

Find the x distance from to .

Divide this up into 4 equal sections.

So then the x distance from to ,

Similarly for the y distance,
Find the y distance from to .

Divide this up into 4 equal sections.

So then the y distance from to ,

So the coordinates of are (5,2).

The line over means
that they are talking about the line segment
joining those two points.

You are looking for the coordinates of a point ,
on that line segment that meets the requirement that
.
In other words,
the distance from to is times
the distance from to .
Dividing the original segment into
equal pieces, is
the"dividing point" closest to .
In this case, if is the midpoint of segment P1P2,
is the midpoint of segment MP2.
