My chemistry experiment says the following "Once K is known, you can find the value of E from the intercept of the straight line with the ordinate axis on your graph. calculate the value of e (in appropriate units) from the values of the intercept, K and b.
E = molar extinction coefficient. at least thats what i think. it looks like a backwards 3. lol
The K value I got which was the slope from the graph I drew was -200
the b is 1.0cm
but how do i get the coefficient from that? at 450nm. anyone? thank you =)

Please describe whole experiment you did.

Would you also define K?  Thanks.
