The slope formula is "rise over run", or 
(y2-y1) / (x2-x1).

Can you compute that?

Do you want the answer or learn how to do it?

anonymous · Answer

both

anonymous · Answer

Try using the slope formula and see what happens.

anonymous · Answer

im working on it

anonymous · Answer

cool :)

anonymous · Answer

its -11

anonymous · Answer

well the numerator is 11 but the bottom (denominator) you probably got 0 right?

anonymous · Answer

so its not a negative its possitive 11

anonymous · Answer

Yeah it's -11, that part you got right, but the bottom of the fraction is 0 - that's the part I was trying to draw your attention to.  What happens when you divide by 0?

anonymous · Answer

You can't divide by 0, it's undefined.  The answer is D.

anonymous · Answer

gradient is undefined
