Can you find the slopes?

anonymous · Answer

Hello my son.

anonymous · Answer

I shalt explain you how to find the slope.

anonymous · Answer

@Ruhhr thou there?

mertsj · Answer

$$\frac{-6-4}{9-(-8)}=\frac{-10}{17}$$

anonymous · Answer

You art correct, Merts.

mertsj · Answer

$$\frac{-2-(-3)}{0-5}=\frac{1}{-5}$$

mertsj · Answer

Well, I see the slopes are not the same.  So....I'll leave the conclusion to you.
