Question

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

Answer 1

Distance in two dimensions is given by:
\[d=\sqrt{(x_{1}-x_{0})^2+(y_{1}-y_{0})^2}\]
Since you know both coordinates, you can solve for the distance by putting in the numbers.

Answer 2

Use the distance formula. The answer is :10 ..... You get the square root of 100, then it becomes 10.
