Question

Medals!!!
Find the distance between the following points:
(-3, 3)(-6, 7).

Answer 1

you can use this
\[D=\sqrt{(y _{b}-y _{a})^2+(x _{b}-x _{a})^2}\]

Answer 2

which one is yb ya xb and xa?

Answer 3

a=(-3,3)
b=(-6,7)
\[D=\sqrt{(-6+3)^2+(7-3)^2}\]
\[\sqrt{9+16}=\sqrt{25}=5\]
but if a=(-6,7) and b=(-3,3) the answer will be the same .
\[D=\sqrt{(-3+6)^2+(3-7)^2}=\sqrt{9+16}=5\]

Answer 4

so its 5?

Answer 5

Answer 7

ummmm hello!!!!!

Answer 8

most students usually say 5 cm. but I can say 5m and 5 km and ... so they usually don't write any thing after 5 .
your Coordinate system can be very big .every square can be 1m^2.so distance between your points can be 5m.

ok thank you!
