Do you know the distance formula?
OpenStudy (anonymous):
no thats why im confused hahah

Do you know pythagorean theorem?
a^2+b^2=c^2
OpenStudy (anonymous):
yup
OpenStudy (anonymous):
what would that help me with doesn't that have to do with finding like a triangle?

okay so lets tart with that. Pythagorean theorem tells us how to find the hypotenuse of a right triangle when we are given the 2 legs.
In this case, you have 2 poitns (x,y)
OpenStudy (anonymous):
ok ;]
OpenStudy (anonymous):
you can find the difference in x (x2-x1) and (y2-y1) to find the two legs
which will form a triangle with the distance (hypotenuse in this case)
OpenStudy (anonymous):
so 6 over 5
OpenStudy (anonymous):
distance formula is

the possible answers that i have are square roots
OpenStudy (anonymous):
so your two legs are 6 and 5. Now go back to pythagorean theorem. The square of the two legs = the square of the hypotenuse.
(leg1)^2 +(leg2)^2 = (hypotenuse)^2
