Question

On the coordinate plane. What is the length of BC if the B coordinate is (1 , 6)

and the C coordinate is (8 , 1) Round to the nearest tenth of a unit.
Which is the correct answer?
- 3.5 units - 8.6 units
- 4.9 units - 15.0 units

Answer 1

You will end up getting 8.6 that will be the answer

Answer 2

You just have to plug your coordinates into the distance formula.
(1, 6) (8, 1)
(X1, Y1) (X2, Y2)

do the work and you get 8.6
