You can put this solution on YOUR website!
Let $\"+b+\"$ = miles that she jogged the 1st week
\n" ); document.write( " $\"+m+=+f%28w%29+\"$ is the function
\n" ); document.write( " $\"+m+=+2w+%2B+b+\"$ is the equation
\n" ); document.write( "----------------
\n" ); document.write( "You are given that $\"+40+=+f%286%29+\"$
\n" ); document.write( " $\"+40+=+2%2A6+%2B+b+\"$
\n" ); document.write( " $\"+40+=+12+%2B+b+\"$
\n" ); document.write( " $\"+b+=+28+\"$
\n" ); document.write( "She jogged 28 mi the 1st week
\n" ); document.write( "The equation is:
\n" ); document.write( " $\"+m+=+2w+%2B+28+\"$
\n" ); document.write( "----------------
\n" ); document.write( " $\"+m+=+60+\"$ mi
\n" ); document.write( " $\"+60+=+2w+%2B+28+\"$
\n" ); document.write( " $\"+2w+=+32+\"$
\n" ); document.write( " $\"+w+=+16+\"$
\n" ); document.write( "After the 16th week she will jog over 60 mi
\n" ); document.write( "-----------------
\n" ); document.write( "Here's the plot:
