yes

anonymous · Answer

Is there even a graph then? I dont understand lol

exoticinspirit · Answer

no just for any math question in general

exoticinspirit · Answer

like if i have the equation y=-2x+1 and 4 graphs and i have to find the right graph that matches

anonymous · Answer

Depends what the Delta Y  Delta X  is
Aka Rise over run

anonymous · Answer

That equation is -2 over 1
So it would go down 2 over 1

anonymous · Answer

And the "+1"is the Y intercept

exoticinspirit · Answer
