First find the slope using the slope formula. Do you know how to do that?

not really

mertsj · Answer

Subtract the y values of the points then subtract the x values of the points in the same order and write a fraction with the y difference on top and the x difference on the bottom.

Wow, that has to be subpar meat. I would call the USDA on that. That stuff can not be good.

mertsj · Answer

2.83 -1.90=.93 and 2010-2000=10 so the slope is .93/10 or .093

And now you are done because all you had to do is find the slope.
