Question

What is the distance between point (2, -2) and (5,3)

A.
3.2 units

B.
4.3 units

C.
5.8 units

D.
7.1 units

Answer 1

Plug it into the distance formula.

Answer 2

@vicyoria15, do you know how to use the distance formula dtan5457 posted?

Answer 3

no not really @jim_thompson5910

Answer 4

what you do is basically subtract the corresponding coordinates and square that difference

so for the x, we subtract: 2-5 = -3
then square -3 to get +9

for the y coordinates, what do you get when you subtract and square the result?

Answer 5

-2-3 is -5 and the you square it and get...25?

Answer 6

very good

Answer 7

now you add those squares: 9+25 = 34

the last step is to take the square root of that to get \(\Large \sqrt{34}\)

Answer 8

which is 5.8?

Answer 9

that's the exact distance

to find the approximate distance, you would use a calculator to evaluate \(\Large \sqrt{34}\)

Answer 10

correct, roughly 5.8

Answer 11

Thank you SOOO much

Answer 12

so all that was using the distance formula
