Algebra.Com's Answer #100711 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Determine the equation of the line. Put in slope-intercept form, if possible. \n" ); document.write( "Through (2,8), perpendicular to 5x+8y=74 \n" ); document.write( "---------- \n" ); document.write( "The given line has slope = -5/8 \n" ); document.write( "So the line you want must have slope 8/5 and must pass thru (2,8) \n" ); document.write( "The form of the equation is y = mx + b \n" ); document.write( "You know y=8 when x=2 and you know m=(8/5); solve for \"b\": \n" ); document.write( "8 = 2(8/5) + b \n" ); document.write( "b = (40/5)-16/5 = 24/5 \n" ); document.write( "-------------------- \n" ); document.write( "EQUATION: \n" ); document.write( "y = (8/5)x + (24/5) \n" ); document.write( "--------------- \n" ); document.write( " \n" ); document.write( "======================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
