Question

find the distance between the points (-5,7) and (4,7)

Answer 1

the formula for computing the distance between 2 points is:

d = sqrt[(x1-x2)^2 + (y1 - y2)^2]
d = sqrt [(-4-5)^2 + (-7-6)^2]
d = sqrt [(-9)^2 + (-13)^2]
d = sqrt [ 81 + 169 ]
d = sqrt (250)
d = 15.811

Answer 2

ah im confused

Answer 3

She is explaining the distance formula to you :P

Answer 4

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

Where \((x_1,y_1)\) and \((x_2,y_2)\) are given points.

Answer 5

In your case, you have (-5,7) and (4,7)

Answer 6

So after plugging in, you should have \(d = \sqrt{(-5-4)^2 + (7-7)^2}\)

Answer 7

Shortcut here is that since you can see that y-coordinates of points are same here.

So this problem basically asks you to find the distance between -5 to 4.

Answer 8

that 10 right

Answer 9

\(4-(-5) = 10\)?

Answer 10

i suck at math so im not sure if im correct

Answer 11

wait it 9

Answer 12

Correct. \(4-(-5) = 4+5 = \boxed 9\)

Answer 13

yeah i did it

Answer 14

two negatives make a positive :)

Answer 15

thank u so much @geerky42

Answer 16

No problem
