You can put this solution on YOUR website!
x-values are the grams of acid produced
\n" ); document.write( "y-values are the minutes taken to make the acid
\n" ); document.write( "(3,32) and (9,48)
\n" ); document.write( "This can be looked at as many ways, but I will do a linear line:
\n" ); document.write( "m = (y2 - y1)/(x2 - x1) = (48 - 32)/(9 - 3) = 16/6 = 8/3
\n" ); document.write( "Use slope-intercept form:
\n" ); document.write( " $\"y+=+mx+%2B+b\"$
\n" ); document.write( " $\"32+=+%288%2F3%29%283%29+%2B+b\"$
\n" ); document.write( " $\"32+=+8+%2B+b\"$
\n" ); document.write( " $\"24+=+b\"$
\n" ); document.write( "so ....
\n" ); document.write( " $\"y+=+%288%2F3%29x+%2B+24\"$
\n" ); document.write( " $\"+graph%28+500%2C+500%2C+-5%2C+10%2C+-5%2C+50%2C+%288%2F3%29x+%2B+24%29+\"$ \n" ); document.write( "
