Answer:

CD = 16.5

Step-by-step explanation:

To find the distance between two points, use this formula: [tex]L = \sqrt{(x_{2} -x_{1})^{2}+(y_{2} -y_{1})^{2} }[/tex]

point C can be info set 1: (10, -1)    x₁ = 10   y₁ = -1

point D can be info set 2: (-6, 3)    x₂ = -6  y₂ = 3

Substitute the information into the formula

[tex]L = \sqrt{(x_{2} -x_{1})^{2}+(y_{2} -y_{1})^{2} }[/tex]

[tex]CD = \sqrt{(-6 -10)^{2}+(3 -(-1))^{2} }[/tex]    Simplify inside each bracket

[tex]CD = \sqrt{(-16)^{2}+(4)^{2} }[/tex]    Square the numbers

[tex]CD = \sqrt{256+16 }[/tex]     Add inside the root

[tex]CD = \sqrt{272}[/tex]    Enter into calculator

[tex]CD = 16.5[/tex]  Rounded to the nearest tenth, the first decimal

The distance CD is 16.5.
