$(\frac{1}{2}, \frac{3}{2})$ , $(- \frac{5}{2}, 2)$

Step 1

Use the distance formula to determine the distance between the two points.

$Distance = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}}$

Step 2

Substitute the actual values of the points into the distance formula.

$\sqrt{{((- \frac{5}{2}) - \frac{1}{2})}^{2} + {(2 - \frac{3}{2})}^{2}}$
