need help
posted by Laurie .
I have this equation y+x=7 I have to graph my answers to find out what my y is. I have tried everything, and I cannot get my points to cross. Any help would be great.

y+x=7
will give you a straight line. Do you have another line or set of points it needs to cross? 
y=x7
what do you mean the points cross. This is a line, it never crosses itself.
