Look at points c and d on the graph:
what is the distance (in units) between points c and d? round your answer to the nearest hundredth.

The distance (in units) between points C and D is 6.70

Step-by-step explanation:

The formula of distance  between 2 Points is  

Distance CD=√(x2−x1)²+(y2−y1)²

In this case,  point C (1,3)

point D (4,-3)

Distance CD=√(4−1)²+(-3−3)²

Distance CD=√(3)²+(-6)²

Distance CD=√9+36

Distance CD=6.70
