Question 167965: So if you have coordinates of:
1620,3
4860,9
that would be 9-4860/3-1620
which=-4851/-1617
slope=3
Am I right?

I'm assuming that you're looking for the slope (and just the slope) right?

Since we're dealing with the points (1620,3) and (4860,9), this means that x%5B1%5D=1620, y%5B1%5D=3, x%5B2%5D=4860, and y%5B2%5D=9


m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 Start with the slope formula.


m=%289-3%29%2F%284860-1620%29 Plug in y%5B2%5D=9, y%5B1%5D=3, x%5B2%5D=4860, and x%5B1%5D=1620


m=%286%29%2F%284860-1620%29 Subtract 3 from 9 to get 6


m=%286%29%2F%283240%29 Subtract 1620 from 4860 to get 3240


m=1%2F540 Reduce


So the slope of the line that goes through the points and is m=1%2F540
