Answer
$d\approx 7.07$
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:
$d=\sqrt{(2.6-1.6)^2+[1.3-(-5.7)]^2}
\\d=\sqrt{1^2+(1.3+5.7)^2}
\\d=\sqrt{1+7^2}
\\d=\sqrt{1+49}
\\d=\sqrt{50}
\\d\approx 7.07$
