If the line defined by the equation -4x+2y=8 crosses another line with the equation y=(2/3)x+b at the point (3,a), what is the value of b? \n" ); document.write( "------------ \n" ); document.write( "If (3,a) satisfies both equations you get: \n" ); document.write( "-12+2a = 8 \n" ); document.write( "a = 2 + b \n" ); document.write( "--- \n" ); document.write( "Substitute for \"a\" and solve for \"b\": \n" ); document.write( "-12 + 2(2+b) = 8 \n" ); document.write( "2+b = 10 \n" ); document.write( "b = 8 \n" ); document.write( "============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============== \n" ); document.write( " \n" ); document.write( " |
