45.0

eviant · Answer

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

Mehek · Answer

Did you use the distance formula?

eviant · Answer

yes

Mehek · Answer

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

eviant · Answer

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

eviant · Answer

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

Mehek · Answer

I think you did the midpoint formula not distance

eviant · Answer

I added those both and came up with 1.5

Mehek · Answer

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

eviant · Answer

oh

Mehek · Answer

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

Mehek · Answer

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

eviant · Answer

I'm coming with 7.8 as the final result?
