Algebra.Com's Answer #629453 by rothauserc(4718) You can put this solution on YOUR website! slope m = (-1 -9) / (1 - (-4)) = -2 \n" ); document.write( "y = -2x + b \n" ); document.write( "-1 = -2 + b \n" ); document.write( "b = 1 \n" ); document.write( "y = -2x + 1, therefore \n" ); document.write( "*************************************** \n" ); document.write( "point slope form is \n" ); document.write( "(y-(-1)) = -2(x-1) \n" ); document.write( "y+1 = -2(x-1) \n" ); document.write( "************************************** \n" ); document.write( "slope intercept form \n" ); document.write( "y = -2x + 1 \n" ); document.write( "************************************* \n" ); document.write( " |
