Use the distance formula.

Answer 4

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

Answer 5

im too slow

Answer 6

okay so can one of you like help me thorugh it beuase i wasn't oaying attention when the teacher taught this and how to input it and etc.

Answer 7

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

Let A (-2,-1) and B(1,2)

Answer 8

x1 = -2
x2 = 1

y1 = -1
y2 = 2

Answer 9

Substitute the values into the above formula.

Answer 10

\[\sqrt{(-2-1)^2 + (-1-2)^2}\]

Answer 11

arehhhh
let me do it haha
