Algebra.Com's Answer #12655 by elima(1433)![]() ![]() ![]() You can put this solution on YOUR website! There are different ways to solve these; \n" ); document.write( "One way; \n" ); document.write( "Put the equation in slope-intercept form; \n" ); document.write( "y=mx+b \n" ); document.write( "m=slope \n" ); document.write( "b=y-intercept \n" ); document.write( "3x+3y=12 \n" ); document.write( "subtract 3x from both sides; \n" ); document.write( "3y=12-3x \n" ); document.write( "Now divide each side by 3 \n" ); document.write( " \n" ); document.write( "y=4-x \n" ); document.write( "Put this in correct form; \n" ); document.write( "y=-x+4 \n" ); document.write( "Solve eqution for y, make x=0; \n" ); document.write( "y=-(0)+4 \n" ); document.write( "y=4 \n" ); document.write( "Now solve for x and make y=0; \n" ); document.write( "0=-x+4 \n" ); document.write( "-4=-x \n" ); document.write( "4=x \n" ); document.write( "So now plot those points on the graph and connect with a line. \n" ); document.write( "Try and solve the others on your own, if you have problems, let me know \n" ); document.write( "=)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
