You can put this solution on YOUR website!
Use the slope intercept form of the line, $\"y=mx%2Bb\"$
\n" ); document.write( "Since you know the intercept,
\n" ); document.write( " $\"y=mx-2\"$
\n" ); document.write( "Now solve for $\"m\"$ using the point.
\n" ); document.write( " $\"1=m%283%29-2\"$
\n" ); document.write( " $\"3m-2=1\"$
\n" ); document.write( " $\"3m=3\"$
\n" ); document.write( " $\"m=1\"$
\n" ); document.write( "So the equation is
\n" ); document.write( " $\"y=x-2\"$
\n" ); document.write( " $\"-x%2By=-2\"$
\n" ); document.write( "Standard form has integer multipliers for x and y and the x coefficient is positive.
\n" ); document.write( " $\"highlight%28x-y=2%29\"$
\n" ); document.write( " \n" ); document.write( "
