Algebra.Com's Answer #273059 by tara0066(31)![]() ![]() You can put this solution on YOUR website! Since the equation you are looking for is perpendicular to the one given, you are going to do a little adjusting to the slope.\r \n" ); document.write( "\n" ); document.write( "The current slope is -4. Your new slope will be the opposite sign and flipped (the reciprocal). If you multiply the two slopes together, you should get negative one.\r \n" ); document.write( "\n" ); document.write( "Your new slope is 1/4.\r \n" ); document.write( "\n" ); document.write( "In slope intercept form as you have it, y=mx+b, you now have your new m or slope and the b is your new y-intercept.\r \n" ); document.write( "\n" ); document.write( "y=1/4x+3 \n" ); document.write( " |
