Can a negative slope be the same as a positive slope? For example, is -4 the same as positive 4 slope.

OpenStudy (skullpatrol):

What do you think?

OpenStudy (yowarning):

i think no

OpenStudy (♥ashley♥):

I dont think they equal the same

OpenStudy (skullpatrol):

-4 is not equal to 4

OpenStudy (skullpatrol):

You are both right!

OpenStudy (retireed):

OpenStudy (yowarning):

OpenStudy (skullpatrol):

Yes, negative slopes down and positive slopes up.

OpenStudy (♥ashley♥):

wait, so is 4/3 the same as -4/3.

OpenStudy (skullpatrol):

Nope.

OpenStudy (♥ashley♥):

so they are different.

OpenStudy (yowarning):

very

OpenStudy (♥ashley♥):

Thanks everyone!

OpenStudy (♥ashley♥):

:)

OpenStudy (skullpatrol):

Yes. They are opposites of each other.

OpenStudy (skullpatrol):

Recall $$\huge a +(-a)=0$$

OpenStudy (skullpatrol):

The only number that is the same as its opposite is 0 Because 0 is neither positive nor negative.

OpenStudy (skullpatrol):

$$-0=0$$

OpenStudy (skullpatrol):

Does that^ make sense?
