help????!!! is this like a grid?

Question

Find the distance between (–3, –2) and (1, 4). Express your answer in simplified radical form.

Answer 1

uh, yeah its the distance between the two points, I think.
The equation you need to use for that is
_________________
/(x2 - x1)^2 + (y2 - y1)^2

x2 being the second x coordinate
x1 being the first x coordinate
y2 being the second x coordinate
y1 being the first x coordinate
^2 meaning squared
__________
/ meaning the square root


(go to http://www.mathwarehouse.com/algebra/distance_formula/index.php to see the equation without the "keyboard limitations")

so you would set up the equation like this:
__________________
/ (1 - {-3})^2 + (4 - {-2})^2
________
/ 4^2 + 6^2
______
/16 + 36
___
/ 52 = 7.21
distance between (-3,-2), (1,4) is 7.21

Since it is in simplified radical form the answer would be 7.21

Answer 2

d = sqrt((4-(-2))^2 + (1 -(-3))^2)
d = sqrt( 6^2+4^2) = sqrt(52) = 2sqrt(13)
