Question

PLEASE HELP!!!!!
Find the distance between the coordinate points (9,-12) and (6,-11)

Answer 1

[3, -1]

Explanation:

lets see here

9 to 6 is just 3 units

-12 to -11 is just 1 unit

so... [3, -1]

why -1?

because when subtracting a negative from a negative is like subtracting a positive from a positive.
