Question

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.

Answer 1

C(1, 3)
D(4, -3)


`CD= √((1-4)^2+(3-(-3))^2) = √((-3)^2+6^2) = √(9+36)= \\ \\=√(45) \approx6.71 \ units`

Answer 2

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

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
