Algebra.Com's Answer #115840 by nerdybill(7384) 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( " |
