Question

ajprincess · Answer

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?

anonymous · Answer

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

anonymous · Answer

I mean is it 7.1 after i round it

ajprincess · Answer

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