Solve each system by graphing both equations on the same axes. give the ordered pair for the point of intersection.
\n" ); document.write( "5x+5y=8
\n" ); document.write( "x=4-y
\n" ); document.write( "**
\n" ); document.write( "Write equations in standard form for straight lines: y=mx+b, m=slope, b=y-intercept
\n" ); document.write( "5x+5y=8
\n" ); document.write( "5y=-5x+8
\n" ); document.write( "y=-x+8/5
\n" ); document.write( "..
\n" ); document.write( "x=4-y
\n" ); document.write( "y=-x+4
\n" ); document.write( "..
\n" ); document.write( "Notice that both equations have the same slope of (-1), therefore, they are parallel lines and do not intersect. See graph below as a visual check on the answer:
