The equation of the line parallel to the line whose equation is 2x+y=0 and passing through the point P(1,-3) is ________
\n" ); document.write( "-----------------
\n" ); document.write( "Parallel lines have the same slope.
\n" ); document.write( "Find the slope of the line by putting it into slope-intercept form.
\n" ); document.write( "2x+y=0
\n" ); document.write( "y = -2x
\n" ); document.write( "The slope, m, = -2
\n" ); document.write( "Then,
\n" ); document.write( "y-y1 = m*(x-x1) where (x1,y1) is the point (1,-3)
\n" ); document.write( "y+3 = -2(x-1)
\n" ); document.write( "y+3 = -2x+2
\n" ); document.write( "y = -2x - 1 slope-intercept form
\n" ); document.write( "2x+y = -1 standard form\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
