## kittykat123 3 years ago Use the Distance Formula to find the distance to the nearest tenth between A(-7, -4) and B(-2, 0).

1. seashell

so you can make sure that you will be able to find the distance

2. Abbie23

Definitely use the distance formula first

3. Abbie23

Yeah, round to the nearest tenth to get a approximate answer

4. kittykat123

Ok but how do I do that?

Use the distance formula, of course

from -2 to -7 is 5 units, from -4 to 0 is 4 units, pythagoras says $$5^2+4^2=d^2$$ so $$d=\sqrt{5^2+4^2}$$

A(-7, -4) and B(-2, 0). D=sqrt(dx^2+dy^2) where dy and dx meand difference in x and y

the formula is $d = \sqrt{(x _{2}-x _{1})^2 + ( y _{2}- y _{1})^2}$ designate the ordered pair A as the 1 point and the other B as the 2 point substitute and evaluate as shown above
