Rate of change and slope.
So the question is "Find the slope of the line that passes through each pair of points"
(2,2) I think it's 1/-1 am I right? or am I not suppose to write it as a fraction just like "-1"?

you have (2,2) but the other point is missing

-3

anonymous · Answer

oops sorry its (2,2),(3,1)

jim_thompson5910 · Answer

m = (y2-y1)/(x2-x1)


m = (1-2)/(3-2)


m = -1/1


m = -1


So the slope is -1 and you are 100% correct

For questions like that, I'm always supposted to simplify and end up with one number? Not a fraction?

jim_thompson5910 · Answer

the idea is to simplify as much as possible

so you reduce as much as possible and if you end up with a fraction it's ok

ex: 4/6 reduces to 2/3

10/2 reduces to 5/1 which is really 5
