Question

Find the perimeter of a triangle with the vertices (2,4) (-1,3) and (2,-3)

Answer 1

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

Answer 2

yea

Answer 3

Then I guess just do that.

Answer 4

ok thanks

Answer 5

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

Answer 6

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

Answer 7

(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)

Answer 8

you dont need slope; you need distance

Answer 9

oops

Answer 10

its still subtract tho ;)
