Answer 1

HI!!

Answer 2

Hey Misty1212

Answer 3

you need the distance formula for this, and also a calculator

Answer 4

My teacher didn't give a formula?

Answer 5

to find the distance compute
\[\sqrt{(6-3)^2+(5+2)^2}\]

Answer 6

the distance between two points is
\[\sqrt{(x_2-x_1)^2+(y_2-y_2)^2}\]

Answer 7

the teacher doesn't give you the formula, mathematics does

Answer 8

pythagoras actually

Answer 9

Oh, Okay.

Answer 10

compute that number, see what you get
