Somewhat, my teacher said that I need to show my solution. I did the graph right

rhondasommer · Answer

y=mx+b
so $$x-y=0$$ subtract x from both sides $$-y=x$$ divide both sides by negative 1$$y=-x$$

rhondasommer · Answer

y=mx+b
so $$3x + y = -4$$ subtract 3x from both sides so $$y=-3x-4$$

rhondasommer · Answer

you can graph both of those :)

rhondasommer · Answer

make more sense?

rhondasommer · Answer

$$y=x$$ sorry mistype on me :/

abbycross167 · Answer

yes ma'am/sir but is that the solution that I need to graph? And where   do I put y=x? @RhondaSommer

rhondasommer · Answer

$$y=mx+b$$
so 
$$x−y=0$$
 subtract x from both sides 
$$−y=-x$$
divide both sides by negative 1
$$y=x$$

:)

abbycross167 · Answer

oh ok, but that is the solution that my teacher was talking about?

rhondasommer · Answer

i have no idea; we can get what x and y equals. we could put it in another equation...youd have to ask

rhondasommer · Answer

did you want to solve for x and y?
