Pick any two ordered pairs represented in the table. Call one of them point 1 and the other one point 2. Subtract the f(x) value for the first point from f(x) value of the second point. Then subtract the x value for the first point from the x value of the second point. Divide the f(x) difference by the x difference. Call that value m.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now replace m and b in \"y=mx%2Bb\" with the values you determined above. \n" ); document.write( "
