What is your question that you want an answer to?
There are about 10 properties that you need to remember.
Answer:
A
Step-by-step explanation
You can divide 6x,9y and -15 by 3
6x/3=2x
9y/3=3y
-15/3=(-5)
Combine them to get the factored form of 6x+9y-15:
3(2x+3y-5)
D(1,-5,-4,-7) R(0,7,-7,-4) Domain are your x values and range is your y values
