How to rotate points given in square grid? 
I really hope you can see this picture.
So My question is 
1) If the figure is rotated 90 degrees counter clock wise about Point O, then:
$$a. G to _________$$ 
$$b. _________ to P $$
How would i rotate i don't even know how to start this?

Get out a piece of trace paper (or such) and trace the image you have shown us. Rotate it $90^\circ$ and see what you get.
As far as coordinates go, a rotation of $90^\circ$ tranforms the point with coordiates $(x,y)$ to a point with coordinates $(-y, x)$. Using $\overleftrightarrow{OF}$ as the $x$-axis and $\overleftrightarrow{ON}$ as the $y$-axis, $G(1,-1)$ becomes the point $E(1,1)$. Let $W(x,y)$ be the point that gets sent to $P(-1,0)$. Then we must have $(-y,x) = (-1,0)$ So $(x,y)=N(0,1)$.
