Question

can someone help me

Answer 1

How many units apart are the points (8, 11) and (-1, -1)?

Answer 2

Well, you can find their distance apart with the distance formula. The formula is as follows:
\[distance=\sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}} \]

So what this means is you take the x2 is the x-coordinate of the 2nd point, x1 is the x-coordinate of the first point. Same thing with the y's. y2 = secondy point, y1 = first y point.

Answer 3

is it 15???

Answer 4

\[\sqrt{(-1-8)^{2}+(-1-11)^{2}}\]
\[\sqrt{(-9)^{2}+(-12)^{2}}\]
\[\sqrt{225 }=15 \]
Good job : )
