# Use the distance formula to find the distance between: (3.5,1) and (-4,2.5)?

$\sqrt{58.5} \approx 7.65$
$d = \sqrt{{\left(\Delta y\right)}^{2} + {\left(\Delta x\right)}^{2}}$
$d = \sqrt{{\left(2.5 - 1\right)}^{2} + {\left(3.5 - \left(- 4\right)\right)}^{2}}$
$d = \sqrt{2.25 + 56.25} \approx 7.65$
