Algebra.Com's Answer #17628 by Nate(3500)![]() ![]() ![]() You can put this solution on YOUR website! let us set the equations is y=mx+b form.....where m is the slope and b is the y-intercept \n" ); document.write( "x -y =7 \n" ); document.write( "-y = -x + 7 \n" ); document.write( "y = x - 7 \n" ); document.write( "--------------------------------------------------------- \n" ); document.write( "3x + y =5 \n" ); document.write( "y = -3x + 5 \r \n" ); document.write( "\n" ); document.write( "the slopes are different, so they are not parallel.... that means the lines are perpendicular; if you combine the equations, you get (3,-4) \n" ); document.write( " |
