y =( -3/5)x +5 and y = x-5
\n" ); document.write( "(-3/5)x + 5 = x-5
\n" ); document.write( "-3x + 25 = 5x - 25
\n" ); document.write( "50 = 8x
\n" ); document.write( "50/8 = x and y = 10/8 \"50%2F8+-+40%2F8\"
\n" ); document.write( "P(50/8, 40/8)
\n" ); document.write( "A = (1/2)10(50/8) = 250/8 = 31.25 units^2
