2. Find the distance between the two points. Round to the nearest tenth if necessary.
Damm [24]

Answer:

\boxed{D = 15.8\ units}

Step-by-step explanation:

The coordinates are (0,9) and (-8,-4)

Distance Formula = \sqrt{(x2-x1)^2+(y2-y1)^2}

D = \sqrt{(-8-0)^2+(-4-9)^2}

D = \sqrt{(-8)^2+(-13)^2}

D = \sqrt{81+169}

D = \sqrt{250}

D = 15.8 units
