Hi, need help with this problem, I have no idea how to even start it.

a)Determining the coordinates of the point N, situated twice near the end R (8.2) as the end S (-1.2) of RS.

Hi;

Do you mean twice as close to R(8,2) as S(-1,2)?

That drawing looks backwards. Shouldn't S be to the left of R?

It means it's closer to R then it is to S. (twice closer)

There was no drawing in the problem, I just did it myself and added the letter in alphabetical order.

If there is something you don't understand in my text, tell me and I'll try to reformulate it. (

Hi;

I understand what you want but have to point out that a coordinate of (-1,2) is to the left of (8,2).

hi Al-Allo

How to start?

(i) Make a graph and plot the points.

(ii) distance between is 9 units

for twice as close divide distance into 3 parts

give 2 parts to S and 1 to R

see diagram.
