Algebra.Com's Answer #144670 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! you need to use the point slope formula which is \n" ); document.write( ": \n" ); document.write( "y-k=m(x-h) where m is the slope and (h,k) is any point on the line \n" ); document.write( ": \n" ); document.write( "we know that any line parallel to -2x-6y=7 has an equal slope. So the first step is to find the slope of this line \n" ); document.write( ": \n" ); document.write( "-2x-6y=7--->-6y=2x+7--->y=(-1/3)x-7/6....so the slope is -1/3 \n" ); document.write( ": \n" ); document.write( "now we have the slope -1/3 and a point (-4,-9).....plug these numbers into our formula above \n" ); document.write( ": \n" ); document.write( "y-(-9)=(-1/3)(x-(-4)) \n" ); document.write( ": \n" ); document.write( "y+9=(-1/3)(x+4) \n" ); document.write( ": \n" ); document.write( "y+9=-1/3x-4/3 \n" ); document.write( ": \n" ); document.write( "y=(-1/3)x-31/3 slope intercept form \n" ); document.write( " |
