The lines 3x+2y-1=0 , 4x+5y=0 intersect at M find the coordinates of M . Equation of the line through M with 3/4 as it's slope
\n" ); document.write( "--------------
\n" ); document.write( "3x+2y = 1
\n" ); document.write( "4x+5y = 0 --> y = -4x/5
\n" ); document.write( "===========
\n" ); document.write( "3x+2y = 1
\n" ); document.write( "sub for y
\n" ); document.write( "3x - 8x/5 = 1
\n" ); document.write( "7x/5 = 1
\n" ); document.write( "x = 5/7
\n" ); document.write( "y = -4/7
\n" ); document.write( "M is (5/7,-4/7)
\n" ); document.write( "=====================
\n" ); document.write( "M with 3/4 as it's slope
\n" ); document.write( "y - y1 = m*(x - x1)
\n" ); document.write( "y + 4/7 = (3/4)*(x - 5/7)
\n" ); document.write( " $\"y+=+3x%2F4+-+31%2F28\"$ \r
\n" ); document.write( "\n" ); document.write( "===================
\n" ); document.write( "it's = it is \n" ); document.write( "
