Question

Are there two distance formulas? 1) d = (x2 - x1)2 + (y2 - y1)2 2) d = (x1 - x2)2 + (y1 - y2)2 I cannot get the right answer with either formula when working with (-1, 2) and (-1, 3) so please help.

Expert Solution

Step 1

Recall:

$Distance formula between the points (x_{1}, y_{1}) and (x_{2}, y_{2}) is d = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}} .$
