Which property was used to simplify the expression?

Communicative property

Step-by-step explanation:

Well there is not multiplication and parenthesis so it’s not distributive

property.

Communicative property is the right answer because there is an equal sign meaning you have to move around the variables and numbers.

It can’t be associative property because there is not substitution.

And finally is not inverse property because no inverse multiplication is needed.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
