You can put this solution on YOUR website!
#5.{2x-2y=4 and y-x=6}
#6.{3x+y=5 and x-y=7}
#7.{-5x+y=-9 and x+3y=21}
#8.{y=x and y-5x=0}
#9. {x=10 and x=y-10}
Put them in slope-intercept form;
#5) y=x-2; y=x+6;
graph+%28300%2C300%2C+-5%2C5%2C-5%2C5%2C+x-2%2C+x%2B6%29
#6) y=-3x+5, y=x-7;
graph+%28400%2C400%2C+-5%2C5%2C-8%2C8%2C+-3x%2B5%2C+x-7%29
#7) y=5x-9, (1/3)x+7;
graph+%28300%2C300%2C+-5%2C5%2C-10%2C10%2C+5x-9%2C+%281%2F3%29x%2B7%29
#8)y=x, y=5x;
graph+%28300%2C300%2C+-5%2C5%2C-5%2C5%2C+x%2C+5x%29
#9)x=10, y=x+10;
graph+%28500%2C500%2C+-5%2C5%2C-11%2C11%2C+x=10%2C+x%2B10%29
