You can put this solution on YOUR website!
Use the \"point slope\" form of a line:
\n" ); document.write( "http://www.purplemath.com/modules/strtlneq2.htm
\n" ); document.write( ".
\n" ); document.write( "y – y1 = m(x – x1)
\n" ); document.write( "The problem gave you:
\n" ); document.write( "a point (1,5) and a slope of -3
\n" ); document.write( ".
\n" ); document.write( "plug it in and solve:
\n" ); document.write( "y – y1 = m(x – x1)
\n" ); document.write( "y – 5 = -3(x – 1)
\n" ); document.write( "y – 5 = -3x + 3
\n" ); document.write( "y = -3x + 8 (this is what they are looking for)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
