Algebra.Com's Answer #133162 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! First, find the slope from: \n" ); document.write( "m = (y2-y1)/(x2-x1) \n" ); document.write( "Given:(-3,7)and (5,-1) \n" ); document.write( ". \n" ); document.write( "m = (-1-7)/(5-(-3)) \n" ); document.write( "m = (-8)/(5+3) \n" ); document.write( "m = (-8)/(8) \n" ); document.write( "m = -1 \n" ); document.write( ". \n" ); document.write( "Now, using the slope (-1) above and one of the two given points say (-3,7) plug it into the point slop form of: \n" ); document.write( "(y-y1) = m(x-x1) \n" ); document.write( "(y-7) = (-1)(x-(-3)) \n" ); document.write( "(y-7) = (-1)(x+3) \n" ); document.write( "y-7 = -x-3 \n" ); document.write( "y = -x + 4 (this is what they're looking for in \"slope intercept\" form) \n" ); document.write( " \n" ); document.write( " |
