1. ## Confusing Problem about graphs.

This problem is worded strangely with no extra info given??

WHAT are the coordinates of the three points that divide the line segment joining P(a,b) and Q(c,d) into four equal parts?

I don't have An idea on this. What we have been doing in class is not similar to this at all.

Thanks

2. familiar with the midpoint formula?

3. ## yes

Yes but, there are no numbers

4. P(a,b), Q(c,d)

The middle point would be...
$M=(\frac {a+c}{2},\frac {b+d}{2})$

Imagine a line segment

P--------M--------Q

We just found M

Now we must find

P---m1---M---m2---Q

The three points that divide up the line segment into 4 parts. Please ignore the crudeness in the drawing.

I've found M(midpoint between P & Q) for you now use the midpoint formula to find m1(the midpoint between P & M) and m2(the midpoint between M & Q)
