Algebra.Com's Answer #38746 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! 1.If a line passes through (2,6) and has the same y-intercept as a line whose equation is x-3y=18 \n" ); document.write( "--------- \n" ); document.write( "The given line has y-intercept (0,-6) \n" ); document.write( "The equation you want is y=mx+b and you need to find m and b: \n" ); document.write( "m=[6--6]/[2-0]=6 \n" ); document.write( "You have y=6,x=2,m=6 so you can solve for b as follows: \n" ); document.write( "6=6(2)+b; b=-6 \n" ); document.write( "EQUATION: y=6x-6\r \n" ); document.write( "\n" ); document.write( "and \n" ); document.write( "2. If a line passes through (2,4) and has the same y-intercept as a line whose equation is x-4y=8. \n" ); document.write( "------------ \n" ); document.write( "Rewrite that equation as 4y=x-8; y=(1/4)x-2 \n" ); document.write( "The given line has slope (1/4) \n" ); document.write( "You have y=4,x=2 and m=(1/4); solve for b as follows: \n" ); document.write( "4=(1/4)2+b \n" ); document.write( "4=(1/2)+b \n" ); document.write( "b=7/2 \n" ); document.write( "EQUATION: \n" ); document.write( "y=(1/4)x+7/2 \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( "\n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
