Question

Find the distance on the coordinate system from the point (-3, 4) to the point (8, -7).

Answer 1

ok, distance formula: \[\sqrt{(x1-y1)+(x2-y2)}\]

Answer 2

you forgot squared symbols, lol

Answer 3

and that's wrong

Answer 4

lol, sorry

Answer 5

\[d=\sqrt{(x-x1)^{2}+(y-y1)^{2}}=\]

Answer 6

ok its \[\sqrt{(x1-y1)^{2}+(x2-y2)^{2}}\]

Answer 7

11sqrt 2

Answer 8

\[d=\sqrt{11^{2}+11^{2}}=...\]

Answer 9

aroub, that still isnt' right...inik got it right

Answer 10

why hero ??

Answer 11

to try to understand it, plot the points and think of the distance as the hypotenuse of right triangle, with the legs being the x,y distances from the points

Answer 12

11 square root of 2 is the answer

Answer 13

distance formula really is just the pythagorean thoerem

Answer 14

heromiles is right.
you can re-write:
\[d=\sqrt{11^{2}+11^{2}}=\sqrt{2*11^{2}}=11\sqrt{2}\]
