Algebra.Com's Answer #118119 by nerdybill(7384) You can put this solution on YOUR website! The equation of the line that goes through the point(3,4) and is parallel to the line going through the points (-6,6) and (1,3) can be written in the form y=mx+b where \n" ); document.write( "m= \n" ); document.write( "b= \n" ); document.write( ". \n" ); document.write( "You already discover that the slope of a line going through the points (-6,6) and (1,3) is \n" ); document.write( "m = -3/7 \n" ); document.write( ". \n" ); document.write( "Now, you have a \"point\" (3,4) and a \"slope\" (-3/7). \n" ); document.write( "Plug it all into the \"point-slope\" form of a line: \n" ); document.write( "y – y1 = m(x – x1) \n" ); document.write( ". \n" ); document.write( "y – 4 = (-3/7)(x – 3) \n" ); document.write( "7y – 28 = (-3)(x – 3) \n" ); document.write( "7y – 28 = -3x + 9 \n" ); document.write( "7y = -3x + 37 \n" ); document.write( ". \n" ); document.write( "Your answer then is: \n" ); document.write( "y = (-3/7)x + (37/7) \n" ); document.write( "m= -3/7 \n" ); document.write( "b= 37/7\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
