Algebra.Com's Answer #28130 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! To find y as a function of x, we merely solve for y in terms of x...thus from \n" ); document.write( "-8x - 5y = -45 \n" ); document.write( "we add 8x to both sides, then divide both sides by -5... \n" ); document.write( "-5y = 8x - 45 \n" ); document.write( "y = (-8/5)x + 9 \n" ); document.write( "I imagine this to be Choice B but you typed it wrong (I edited it) \n" ); document.write( " |
