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

1. seashell Group Title

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

2. Abbie23 Group Title

Definitely use the distance formula first

3. Abbie23 Group Title

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

4. kittykat123 Group Title

Ok but how do I do that?

6. Abbie23 Group Title

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
