Question

Find the distance d(A,B) between points A and B
A(2.-6), B(2.1)
d(A,B) =

Answer 1

7 units

Explanation:

Since the x coordinates are the same, we only have to look at the difference between the y coordinates to determine the distance

1 - -6 = distance

1+6 = 7

The distance is 7 units

Answer 2

d = 7

Explanation:

Distance Formula:
`d = √((x2 - x1)^2+(y2-y1)^2)`

Plug in our 2 coordinates:

`d = √((2-2)^2+(1+6)^2)`

And you should get 7 as your final answer.
