Question

What is the distance between points (9, 4) and (–3, 4) on a coordinate plane?

Answer 1

Use the distance formula.

Answer 2

what is that

Answer 3

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

Answer 4

(9, 4), (-3, 4)
x1 y1 x2 y2

Answer 5

so I have to complete the fomula

Answer 6

I am confused

Answer 7

yes. replace the x1 ,x2 and y1, y2 with the numbers.

Answer 8

Yes

Answer 9

\(\sf d = \sqrt{(-3-9)^2 + (4-4)^2}\)

Answer 10

yes. now solve it

Answer 11

Oh, well since they have the same y-value, we can just subtract the two numbers.

|9 - (-3)|

Answer 12

how do I solve it

Answer 13

Just subtract

|9 - (-3)|

Answer 14

have you learned subtraction addition and multiplication?

Answer 15

yes but that thing with all the numbers how do I do that

Answer 16

igreen has got it down where now all u have to do is subtract 9 from -3

Answer 17

d= what is that

Answer 18

dont worry about that part. we are solving for D, as of right now D doesnt matter

Answer 19

12

Answer 20

d represents the distance.

Answer 21

12=9 - -3

Answer 22

no D= 9-(-3) then when u solve that D=12

Answer 23

see what i am talking about?

Answer 24

ya

Answer 25

so your distance is 12

Answer 26

ya

Answer 27

problema resuelto

Answer 28

what

Answer 29

problem solved

Answer 30

okay
