There are two given points (x_{1}, y_{1}) and (x_{2}, y_{2}), the distance between these points is prearranged by the formula:
Don't allow the subscripts fright you. They only signifies that there is a "first" point and a "second" point; i.e. that you have two points. Either you can call "first" or "second" is up to you. The distance will be the similar, besides.
For Example
Determine the distance between the points (-2, -3) & (-4, 4).
I simply put the coordinates into the Distance Formula:
Then the distance is sqrt(53), or approximately 7.28, rounded off to two decimal places.
