All you need to know is the formula for finding the slope of a line.
That formula is this:

%28y%5B1%5D+-+y%5B2%5D%29/%28x%5B1%5D+-+x%5B2%5D%29

Hm. I wish I could make that look better, but let me just say that this %28y%5B1%5D+-+y%5B2%5D%29 is the numerator and this %28x%5B1%5D+-+x%5B2%5D%29 is in the denominator.

Ok, so your ordered pairs are: (-1,-1) and (0,0)

Therefore, you would just say:

%28-1+-+0%29/-1+-+0%29 which is
%28-1%29%2F%28-1%29 which is
1%2F1 or just 1.

Your slope, or your "m" is 1.

I hope this helps you. :-)

Find the slope
m=%28y2-y1%29%2F%28x2-x1%29
m=%280-%28-1%29%29%2F%280-%28-1%29%29=1%2F1=1
