Question

Check my answer: Karen plotted the route of a city tour bus on a coordinate grid. It shows the route as a quadrilateral with vertices at J(1, 1), K(2, 9), L(10, 8), and M(9, 0).
Which statement about the bus route is true?
It is a square of side length 1 unit.
It is a square of side length 3sqr7 units.
It is a square of side length sqr65 units.
It is a square of side length 8 units.
i got c

Answer 1

Answer 2

Its right. Good work.

Answer 3

well, they was nice enough to say its a square ....

id move the first 2 points to the so that one of them is at the origin

Answer 4

The answer is c) Square having each side = sqrt 65 units.

Answer 5

1,1 2,9
-1-1 -1-1
-------------
0,0 1,8 <- d that up

Answer 6

sqrt65 is fine to me too

Answer 7

Thanks guys :)

Answer 8

Use the distance formula to check the answer : \(x_1 , y_1 \) and \(x_2 , y_2\) : distance between the two points : \(\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2 }\)
