Answer
$d\approx 4.47$
Work Step by Step
RECALL:
The distance between the points $(x_1, y_1)$ and $x_2, y_2)$ can be found using the distance formula:
$d=\sqrt{x_1-x_2)^2+(y_1-y_2)^2}$
Solve for the distance between the two points using the formula above to obtain:
$d=\sqrt{[3.5-(-0.5)]^2+(8.2-6.2)^2}
\\d=\sqrt{(3.5+0.5)^2+2^2}
\\d=\sqrt{4^2+2^2}
\\d=\sqrt{16+4}
\\d=\sqrt{20}
\\d\approx 4.47$
