Question

What is the distance between (2, -1) and (-1, -5) on the coordinate plane?

7 units
6 units
5 units
4 units

Answer 1

@daniellecrook this is so easy if i had a graph

Answer 2

6 units

Answer 3

it is 6 units

Answer 4

@dlxhazedxlb how did u find out

Answer 5

i found it out @ivanapen8

Answer 6

lol you guys... I don't think so :)

Answer 7

@terenzreignz what say it to my face

Answer 8

is this u

Answer 9

Oh no, I wasn't addressing you, @ivanapen8
Only the guys that said it was 6 units.. and anyway, it'd be nicer if you show how to get it :)

Behold the distance formula...
\[\Large d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\]

Answer 10

@terenzreignz oh ok : - ) im bad at math

Answer 11

plugging in those values results in
\[\Large d = \sqrt{(-1-2)^2 + (-5+1)^2}\]\[\Large d = \sqrt{(-3)^2 + (-4)^2}\]\[\Large d = \sqrt{9 + 16}\]\[\Large d = \sqrt{25}\]\[\huge \color{blue}{d=5}\]
