Somebody help please!!
OpenStudy (mathwizzard3):
What do you think you should do?
OpenStudy (mathwizzard3):
To find the distance
OpenStudy (melody323):
I don't know
OpenStudy (mathwizzard3):
I would say the distance formula. By any chance to you know what the formula is?

OpenStudy (melody323):
No sorry
OpenStudy (mathwizzard3):
Distance = \[\sqrt{ (x (two) - x (one))^2 + (y(two) - y (one))^2 }\]
OpenStudy (mathwizzard3):
this means the second x coordinate - the first x coordinate
OpenStudy (melody323):
Oh ok
OpenStudy (melody323):
Can you give me an example?

@rebeccaxhawaii
OpenStudy (mathwizzard3):
lets say we have points (9,7) and (11, 10)
OpenStudy (melody323):
ok
OpenStudy (mathwizzard3):
the second x coordinate would be 11
OpenStudy (mathwizzard3):
the first x coordinate would be 9

OpenStudy (mathwizzard3):
so it would be 11-9
OpenStudy (mathwizzard3):
so why don't we find the coordinates first
OpenStudy (melody323):
For the equation i got (-3,1) (2,2). Which would be ( -3 - 2)
rebeccaxhawaii (rebeccaxhawaii):
plug in your points

(-3, -1) and (2,2)
OpenStudy (melody323):
oh ok
OpenStudy (mathwizzard3):
so if we plug it in it is the square root of (2 -(-3)^2 + (2-(-1)^2
OpenStudy (mathwizzard3):
so what is 2-(-3)?
OpenStudy (melody323):
5

OpenStudy (mathwizzard3):
yup and what about (2-(-1)
OpenStudy (melody323):
3
OpenStudy (mathwizzard3):
so if we plug it in it is the square root of (5)^2 + (3)^2
OpenStudy (mathwizzard3):
SO if you square them it is 25 + 9
OpenStudy (mathwizzard3):
the square root of 25 + 9

OpenStudy (mathwizzard3):
so the square root of 34 is your answer
OpenStudy (melody323):
ok thanks
OpenStudy (melody323):
Can you help me with another one?
OpenStudy (mathwizzard3):
Sure!
OpenStudy (melody323):
I gonna post up.
