Question

A marina is in the shape of a coordinate grid. Boat A is docked at (4.2, −2) and Boat B is docked at (−5.2, −2). The boats are ____ units apart. A) 6.2 B) 7.2 C) 9.4 D) 13.4

Answer 1

Your answer will be D.

Explanation:

I did it on the test and got it correct.

Answer 2

The distance between any two points is:

d^2=(x2-x1)^2+(y2-y1)^2

d^2=(4.2--5.2)^2+(-2--2)^2

d^2=(9.4)^2

d=9.4
