In studying the "ozone-deficit" problem (Science, September 23, 1994, page 1835), one experiment measured laser-induced fluorescence (LW) at various ozone partial pressures, obtaining the following results:

a. Find the equation of the best-fitting straight line.
b. Interpret the slope.
c. Predict the L1F intensity if the ozone partial pressure is 37 .
d. Predict what ozone partial pressure would result if the L1F intensity was 18.
