PLS HELP!!!
Find the distance between R(–1, 1) and S(–4, –5) to the nearest tenth.

Answer 1

6.7


9.0


15.8


45.0

Answer 2

@Vocaloid I came up w/ 1.5, but that's not an option

Answer 3

Did you use the distance formula?

Answer 4

yes

Answer 5

Do you have your work? Maybe I can see where you went wrong

Answer 6

so, I did: -1-4/2 which is -2.5

Answer 7

then I did -1+5/2 which is 4

Answer 8

I think you did the midpoint formula not distance

Answer 9

I added those both and came up with 1.5

Answer 10

Distance formula is
\(\bf\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\)

Answer 11

oh

Answer 12

So let's plug in the values
x1 would be -1, x2 would be -4, y1 would be 1, and y2 would be -5

Answer 13

Plugging them:
\(\bf\sqrt{(-5-1)^2+(-4--1)^2}\)
Could you solve that

Answer 14

I'm coming with 7.8 as the final result?

Answer 16

I got something different

Answer 17

Ok let's do this step by step
