Question

Find the distance for the following points A ( -2, -3) B (-7, -8). If necessary round your answer to the nearest tenth.

Answer 1

For two points
\[(x_1,y_1)\space(x_2,y_2)\]
\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
Can u do nw?

Answer 2

I dont understand answer choices are
1) 11
2) 7.1
3) 7
4) -7.1

Answer 3

I mean is it 7.1 after i round it

Answer 4

U hav points (-2,-3) and (-7,-8)
Applying this in
\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
\[=\sqrt{(-7-(-2))^2+(-8-(-3))^2}\]
\[=\sqrt{(-7+2)^2+(-8+3)^2}\]
\[=\sqrt{(-5)^2+(-5)^2}\]
\[=\sqrt{25+25}\]
\[=\sqrt{50}\]
\[=7.07\]
\[=7.1\]

Answer 5

is it clear nw?
