I am trying to figure out the concentrations of certain compounds, and I am a bit stumped on the response factor.

I have read the response factor is = Peak size/Known amount of component, but yet I also read that the response factor is = m(slope)*concentration of standard. 

If my concentration of standards going into the GC FID  with certain peak areas and peak heights:
C2-100ppmv
C3-101ppmv
C4-100ppmv
C5-103ppmv
C6-102ppmv

Then when I analyze the analyte and I get an Peak area and Peak height along with the time.  Basically what I asking is the correct way to figure out response factor.

If C is concentration, A - Peak area, K - response factor.

The most common definition:
A=K*C. As an example: Response factor is zero, means that instrument gives no response (no signal) on a particular compound.

at the same time I often see a reverse formula, which makes calculations a little bit easier (as your instrument generates A):

C=K*A
