Question

anonymous · Answer

to find the distance (or units) apart between two points $$\large (x_1,y_1)~~and~~(x_2,y_2)$$
$$\large D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$$
D is the distance (or units ) apart between the two points.

anonymous · Answer

I don't remember how to do any of this

anonymous · Answer

i have given you the formula.......can you do it now?

anonymous · Answer

d = √(8- -1)^2 + (11 -1)^2
d = √9^2 + 10^2

anonymous · Answer

it is supposed to be    (11- -1)^2

anonymous · Answer

after you have corrected the mistake, what do you get??

anonymous · Answer

d = √9^2 + 12^2
d= √81 + 144
d = √225
d = 15?

anonymous · Answer

yes....
.....same as i got

You could of just counted on a graph how far apart they were. LOL its not that hard.
