Question

Help please i will medal and fan: Find the distance between the points on the coordinate plane.

Points B and (–1, 2)

A.
3


B.
4


C.
5


D.
6

Answer 1

Heres the graph

Answer 2

can you tell me co-ordinate of point B first ?

Answer 3

(5 2)

Answer 4

thats correct, now you have both points, use the distance formula!

Answer 5

Distance between points (x1,y1) and (x2,y2) is
\(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)
does this help ??

Answer 6

Um?

Answer 7

Not really :/ But thanks

Answer 8

the 2 points are
x1, y1 = -1,2
x2, y2 = 5,2

so just plug in
x1 = -1
y1 = 2
x2 = 5
y2=2
in that formula!

Answer 9

ok.....

Answer 10

..

Answer 11

I have no idea what u said but ill medal and fan

Answer 12

\(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2} \\ \huge d=\sqrt{(-1-5)^2+(2-2)^2}\)

Answer 13

what is -1-5 = ... ?

Answer 14

4

Answer 15

not actually

-1 -5 = - (1+5) = -6
got this ?

Answer 16

Yes Thank you very mcuh

Answer 17

\( \huge d=\sqrt{(-1-5)^2+(2-2)^2} \\ \Large d = \sqrt{(-6)^2+0} = \sqrt{36}=6\)
thats how we solve distance formula related problems :)

Answer 18

Ok ill write that on my notebook :) Thank you.

Answer 19

welcome ^_^
