Question

help plz fan and medal

Answer 1

Find the distance between the points on the coordinate plane.

points A and (2, –2)



A.
–4

B.
2

C.
4

D.
6

Answer 2

use formula distance b/w two points (x1,y1) and (x2,y2) is d=sqrt{(x2-x1)^2+(y2-y1)^2}

Answer 3

Identify the coordinates of point A. Then use the distance formula.

Answer 4

The coordinates of point A are readable directly from your posted diagram.

Answer 5

so is it 4

Answer 6

Please show all of your work, OK? "Right" or "wrong" doesn't say much.

Answer 7

i dont get it

Answer 8

@mathmale

Answer 9

Hi @kingjames56
ready to start solving it?

Answer 10

yes

Answer 11

Ok,
Do you know what Cartesian Coordination is?

Answer 12

A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length.

Answer 13

Now tell me which point has coordinates (1,2) ?

Answer 14

A, B or C?

Answer 15

b

Answer 16

Why B?

Answer 17

No!
It's A.
Because by (1,2) we mean x=1 and y=2
ok?

Answer 18

you got it?

Answer 19

yes

Answer 20

very good.
Now let's concentrate on the distance:
the distance between two points (x1,y1) and (x2,y2) can be calculated this way:
\[d=\sqrt{(x2-x1)^2+(y2-y1)^2}\]

Answer 21

I give you an example:
What is the distance between points A and B here:
A (1,1) and B (4,5)

\[d=\sqrt{(4-1)^2+(5-1)^2}=\sqrt{3^2+4^2}=\sqrt{25}=5\]
Do you understand this?

Answer 22

yes

Answer 23

i think the answer is 2 idk im not for sure

Answer 24

Very good.
So the only thing you need to do is
1) finding coordinates of the two points.
2) substituting them in the formula above

What are the coordinates of the two points in your question?

Answer 25

thanks for helping me

Answer 26

It's not correct.
Do not give up till it's finished.

Firstly tell me what are the coordinate of two points in your question.

Answer 27

(2, –2)

Answer 28

points A and (2, –2)

Answer 29

I know. What is the coordinate of point A?
Look at the picture and tell.

Answer 30

(2, –2)

Answer 31

(2,2)

Answer 32

bye i have to go

Answer 33

you still can answer them ima see it in my gmail

Answer 34

It's correct now.
Put it in the equation and solve it

Remember that 2-(-2)=2+2=4

Do Great!
