Question

-x-y=1 
find three points to solve the equation, then plot them on a graph

anonymous · Answer

if i am understanding this right this is really simple

anonymous · Answer

all you have to do is plug in x and y values that make the equation true

anonymous · Answer

okaii so can u give meh some help to break it down

anonymous · Answer

okay, what 2 numbers can you replace the x and the y with to equal 1

anonymous · Answer

1 and 2

anonymous · Answer

probably easier just to pick an $x$ and find the $y$
i pick $x=3$ then $-3-y=1$ so $-y=4$ making $y=-4$
now i have the point $(3,-4)$

anonymous · Answer

or you could make it even easier by taking 
$$-x-y=1 $$ and solve for $y$
you get 
$$-y=x+1$$ so 
$$y=-x-1$$ now when you pick an $x$ you already have $y$ solved for
i pick $x=7$ so $y=-7-1=-8$ giving me the point $(7,-8)$
