What is the distance between the points (-4, -9) and (-8, -5)?

Question

parthkohli · Answer

First find the distance between the x coordinates, then find the distance between y coordinates.

parthkohli · Answer

When you actually draw two lines from x1 to x2 and then y1 to y2, you'll notice that the hypotenuse is the distance :)

shane_b · Answer

$$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$$

parthkohli · Answer

No need to learn all those formulas haha they sometimes really get you confused :)

shane_b · Answer

That's an easy one though...no drawing involved :)

parthkohli · Answer

Haha lol you must not draw.

shane_b · Answer

I draw like a 4 year old!

parthkohli · Answer

Like the distance between -4 and -8 is 4.
Distance between -9 and -4 is 4.
The hypotenuse can be found by $c^2 = 4^2 + 4^2$

parthkohli · Answer

$c^2 = 32$

$ \color{Black}{\Rightarrow c = \sqrt{32} }$

Simplify it.

anonymous · Answer

you can make it become a vector then find the length of that vector
$$\sqrt{(x2-x1)^2 + (y2-y1)^2}$$ = distance

We already covered that :)
