Question

nottim · Answer

You should really just graph it. Are you allowed to?

anonymous · Answer

yea

nottim · Answer

Then I guess just do that.

anonymous · Answer

ok thanks

nottim · Answer

If you get any problems with diagonals, remember, slope= y2-y1/x2-x1. Ok?

nottim · Answer

Or, subtract the "1st point" from the "2nd point".

(2,4) (-1,3) and (2,-3)
-2-4 -2-4        -2-4
-----------------
 0,0   -3,1         0,-7
          sqrt(10)      7

(2,4) (-1,3) and (2,-3)
1-3    1-3          1-3
--------------------
3,1     0,0            3,0
sqrt(10)                 3


7+3+sqrt(10) = 10+sqrt(10)

amistre64 · Answer

you dont need slope; you need distance

nottim · Answer

oops

amistre64 · Answer

its still subtract tho ;)
