Question

How many units apart are the points (4, -3) and (-4, 3)?

Answer 1

Use:

\[\large Distance = \sqrt{(x_2 - x_1)^2+ (y_2 - y_1)^2}\]

\[\large x_2 = -4, x_1 = 4, y_2 = 3, y_1 = -3\]

Plug in the values and find the distance..

Answer 2

0?

Answer 3

You are not taking care of negative signs..

\[Distance = \sqrt{(-4-4)^2 + (3 - (-3))^2}\]

Answer 4

-4 -4 = -8

and:

3 - (-3) = 3 + 3 = 6

Answer 5

so 2 ?

Answer 6

How??
