Algebra.Com's Answer #199629 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Ok, you've done everything right so far. \n" ); document.write( "-5 = -3(4)+b Simplify the right side of the equation. \n" ); document.write( "-5 = -12+b Now add 12 to both sides. \n" ); document.write( "7 = b Now write the final equation in slope-intercept form: y = mx+b. \n" ); document.write( "y = -3x+7 \n" ); document.write( " |
