You can put this solution on YOUR website!
The slope-intercept form of
\n" ); document.write( "a linear equation is:
\n" ); document.write( " $\"+y+=+m%2Ax+%2B+b+\"$
\n" ); document.write( " $\"+m+\"$ = slope
\n" ); document.write( " $\"+b+\"$ = y-intercept
\n" ); document.write( "--------------------------
\n" ); document.write( "You are given:
\n" ); document.write( " $\"+m+=+3+\"$
\n" ); document.write( "So far you have:
\n" ); document.write( " $\"+y+=+3x+%2B+b+\"$
\n" ); document.write( "--------------------------
\n" ); document.write( "Plug in the given point:
\n" ); document.write( "( -5, 4 )
\n" ); document.write( " $\"+4+=+3%2A%28-5%29+%2B+b+\"$
\n" ); document.write( " $\"+4+=+-15+%2B+b+\"$
\n" ); document.write( " $\"+b+=+19+\"$
\n" ); document.write( "--------------------------
\n" ); document.write( "The equation is:
\n" ); document.write( " $\"+y+=+3x+%2B+19+\"$
\n" ); document.write( "---------------------------
\n" ); document.write( "check:
\n" ); document.write( "( -5,4 )
\n" ); document.write( " $\"+4+=+3%2A%28-5%29+%2B+19+\"$
\n" ); document.write( " $\"+4+=+-15+%2B+19+\"$
\n" ); document.write( " $\"+4+=+4+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
